Resumen
Functional nanomaterials possess exceptional mechanical, electrical, and optical properties which have significantly benefited their diverse applications to a variety of scientific and engineering problems. In order to fully understand their characteristics and further guide their synthesis and device application, the multiphysical properties of these nanomaterials need to be characterized accurately and efficiently. Among various experimental tools for nanomaterial characterization, scanning electron microscopy- (SEM-) based platforms provide merits of high imaging resolution, accuracy and stability, well-controlled testing conditions, and the compatibility with other high-resolution material characterization techniques (e.g., atomic force microscopy), thus, various SEM-enabled techniques have been well developed for characterizing the multiphysical properties of nanomaterials. In this review, we summarize existing SEM-based platforms for nanomaterial multiphysical (mechanical, electrical, and electromechanical) in situ characterization, outline critical experimental challenges for nanomaterial optical characterization in SEM, and discuss potential demands of the SEM-based platforms to characterizing multiphysical properties of the nanomaterials.

Resumen
Migration of atoms is presented to be utilized for fabrication of metallic micro/nanomaterials by controlling the phenomenon. Two kinds of migration phenomena are treated; one is electromigration and the other is stress migration. In addition to the formation of micro/nanomaterials, some achievements in enhancing their functions are demonstrated. One is a technique to fabricate nanocoils from the formed Cu nanowires. The others are techniques to weld or cut the micro/nanowires by using Joule heating. Finally, regarding evaluation of mechanical and electrical properties of the micro/nanomaterials, the concentrated-mass cantilever technique in atomic force acoustic microscopy and the four-point atomic force microscope technique are shown to be powerful tools, respectively.

Resumen
Novel nanobiomaterials are increasingly gaining ground in bioengineering research. Among the numerous biomaterials, collagen-nanobiomaterials, such as collagen thin films, are of great interest since they present a wide range of applications in the fields of biomaterials, tissue engineering, and biomedicine. Collagen type I is the most abundant protein within extracellular matrix and, due to its unique characteristics, is widely used as biomaterial. A thorough characterization of the structure and properties of nanomaterials can be achieved by Atomic Force Microscopy (AFM). AFM is a very powerful tool which can be used to obtain qualitative or quantitative information without destroying the collagen fibrillar structure. This mini review covers issues related to the use of AFM for studying the structure and mechanical properties of collagen-based nanobiomaterials, collagen-substrate interactions during the formation of collagen thin films, collagen-cells interactions, and the collagen-optical radiation interactions.

Resumen
Given the social demand for self-powering wearable electronics, it is necessary to develop composite materials that exhibit both good flexibility and excellent piezoelectric performances. Intensive research on synthesis methods and devising characterization techniques for piezoelectric nanomaterials in various forms has been conducted. In particular, characterization techniques for piezoelectric nanomaterials require different approaches from those for conventional bulk materials. Atomic force microscopy (AFM)-based characterization techniques work based on the local physical interactions between the AFM tip and sample surfaces, making them an irreplaceable tool for studying the electromechanical properties of piezoelectric nanomaterials. Piezoresponse force microscopy (PFM), conductive AFM (C-AFM), and lateral force microscopy (LFM) are three representative AFM-based techniques used to characterize the piezoelectric and ferroelectric properties of nanomaterials. Coupled with the appearance of diverse novel nanomaterials such nanowires, free-standing nanorods, and electrospun nanofibers, AFM-based characterization techniques are becoming freer from artifacts and the need for quantitative measurements. PFM was initially developed to image the microstructures of piezoelectric materials, and well-calibrated techniques designed to realize quantitative measurements have been applied to nanomaterials. In contrast, C-AFM and LFM were initially used to measure the conductivity of diverse materials and the nanotribology of material surfaces. Over the last decade, they have proved their versatility and can now be used to evaluate the direct piezoelectric effect and the mechanical properties of piezoelectric nanomaterials. In these cases, systematic understanding with regard to the measurement principles is required for accurate measurements and analyses. In the present review article, we discuss earlier work in which AFM-based electromechanical characterization techniques were applied to nanomaterials to evaluate piezoelectric and ferroelectric properties. Also discussed is the importance of gaining a comprehensive understanding of the resulting signals.

Resumen
Atomic force microscopy (AFM) can characterize nanomaterial elasticity. However, some one-dimensional nanomaterials, such as DNA, are too small to locate with an AFM tip because of thermal drift and the nonlinearity of piezoelectric actuators. In this study, we propose a novel approach to address the shortcomings of AFM and obtain the radial Young’s modulus of a DNA duplex. The elastic properties are evaluated by combining physical calculations and measured experimental results. The initial elasticity of the DNA is first assumed; based on tapping-mode scanning images and tip–sample interaction force simulations, the calculated elastic modulus is extracted. By minimizing the error between the assumed and experimental values, the extracted elasticity is assigned as the actual modulus for the material. Furthermore, tapping-mode image scanning avoids the necessity of locating the probe exactly on the target sample. In addition to elasticity measurements, the deformation caused by the tapping force from the AFM tip is compensated and the original height of the DNA is calculated. The results show that the radial compressive Young’s modulus of DNA is 125–150 MPa under a tapping force of 0.5–1.3 nN; its original height is 1.9 nm. This approach can be applied to the measurement of other nanomaterials.

Resumen
This paper provides a comprehensive review on the methodological development and technical applications of in situ microscopy, including transmission electron microscopy (TEM), scanning electron microscopy (SEM) and atomic force microscopy (AFM), developed in the last decade for investigating the structure-mechanical-property relationship of a single one-dimensional nanomaterial, such as nanotube, nanowire and nanobelt. The paper covers both the fundamental methods and detailed applications, including AFM-based static elastic and plastic measurements of a carbon nanotube, external field-induced resonance dynamic measurement of elastic modulus of a nanotube/nanowire, nano-indentation, and in situ plastic deformation process of a nanowire. Details are presented on the elastic property measurements and direct imaging of plastic to superplastic behavior of semiconductor nanowires at atomic resolution, providing quantitative information on the mechanical behavior of nanomaterials. The studies on the Si and SiC nanowires clearly demonstrated their distinct, "unexpected" and superior plastic mechanical properties. Finally, a perspective is given on the future of nanomechanics.

Resumen
Incorporation of silver nanoparticles (AgNPs) into an increasing number of consumer products has led to concern over the potential ecological impacts of their unintended release to the environment. Dissolution is an important environmental transformation that affects the form and concentration of AgNPs in natural waters; however, studies on AgNP dissolution kinetics are complicated by nanoparticle aggregation. Herein, nanosphere lithography (NSL) was used to fabricate uniform arrays of AgNPs immobilized on glass substrates. Nanoparticle immobilization enabled controlled evaluation of AgNP dissolution in an air-saturated phosphate buffer (pH 7, 25 °C) under variable NaCl concentrations in the absence of aggregation. Atomic force microscopy (AFM) was used to monitor changes in particle morphology and dissolution. Over the first day of exposure to ⠥10 mM NaCl, the in-plane AgNP shape changed from triangular to circular, the sidewalls steepened, and the height increased by 6-12 nm. Subsequently, particle height and in-plane radius decreased at a constant rate over a 2-week period. Dissolution rates varied linearly from 0.4 to 2.2 nm/d over the 10-550 mM NaCl concentration range tested. NaCl-catalyzed dissolution of AgNPs may play an important role in AgNP fate in saline waters and biological media. This study demonstrates the utility of NSL and AFM for the direct investigation of un-aggregated AgNP dissolution.

Resumen
Studying physical properties of nanoscale materials has gained a significant attention owing to their applications in the fields such as electronics, medicine, pharmaceutical industry, and materials science. However, owing to size constraints, number of techniques that measures physical properties of materials at nanoscale with a high accuracy and sensitivity is limited. In this context, development of atomic force microscopy (AFM) based techniques to measure physical properties of nanomaterials has led to significant advancements across the disciplines including chemistry, engineering, biology, material science and physics. AFM has recently been utilized in the quantification of physical-chemical properties such as electrical, mechanical, magnetic, electrochemical, binding interaction and morphology, which are enormously important in establishing structure-property relationship. The overarching objective of the investigations discussed here is to gain quantitative insights into the factors that control electrical and mechanical properties of nano-dimensional organic materials and thereby, potentially, establishing reliable structure-property relationships particularly for organic molecular solids which has not been explored enough. Such understanding is important in developing novel materials with controllable properties for molecular level device fabrication, material science applications and pharmaceutical materials with desirable mechanical stability. First, we have studied electrical properties of novel silver based organic complex in which, the directionality of coordination bonding in the context of crystal engineering has been used to achieve materials with structurally and electrically favorable arrangement of molecules for an enhanced electrical conductivity. This system have exhibited an exceptionally high conductivity compared to other silver based organic complexes available in literature. Further, an enhancement in conductivity was also observed herein, upon photodimerization and the development of such materials are important in nanoelecrtonics. Next, mechanical properties of a wide variety of nanocrystals is discussed here. In particular, an inverse correlation between the Young’s modulus and atomic/molecular polarizability has been demonstrated for members of a series of macro- and nano-dimensional organic cocrystals composed of either resorcinol (res) or 4,6-di-X-res (X = Cl, Br, I) (as the template) and trans-1,2-bis(4-pyridyl)ethylene (4,4’-bpe) where cocrystals with highly-polarizable atoms result in softer solids. Moreover, similar correlation has been observed with a series of salicylic acid based cocrystals wherein, the cocrystal former was systematically modified. In order to understand the effect of preparation method towards the mechanical properties of nanocrystalline materials, herein we have studied mechanical properties of single component and two component nanocrystals. Similar mechanical properties have been observed with crystals despite their preparation methods. Furthermore, size dependent mechanical properties of active pharmaceutical ingredient, aspirin, has also been studied here. According to results reduction in size (from millimetre to nanometer) results in crystals that are approximately four fold softer. Overall, work discussed here highlights the versatility of AFM as a reliable technique in the electrical, mechanical, and dimensional characterization of nanoscale materials with a high precision and thereby, gaining further understanding on factors that controls these processes at nanoscale.

Resumen
The enhancement of strength of nanoscale materials such as face-centered cubic metal nanowires is well known and arises largely from processes mediated by high energy surface atoms. This leads to strong size effects in nanoscale plasticity; ,smaller is stronger. Yet, other factors, such as crystalline defects also contribute greatly to the mechanical properties. In particular, twin boundaries, which are pervasive and energetically favorable defects in face-centered cubic metal nanowires, have been shown to greatly enhance the strength, furthermore this increase in strength has been shown to be directly influenced by the twin density. However, attempts to control the introduction of beneficial defects remains challenging. Additionally, even minor local variations in the crystalline structure or size of metal nanowires may have drastic effects on the yielding of metal nanowires, which are difficult to measure through tensile and bending tests. In this study, atomic force microscopy based nanoindentation techniques are used to measure the local plasticity of Ni-Au bimetallic as well as Cu and Ag metallic nanowires. In the first part of the thesis the hardness of bimetallic nanowires synthesized through template-assisted electrodeposition is measured and found to show significant size-effects. It was found that the nanoindentation hardness was governed by materials properties, the observed indentation size effects were dependent on geometrical factors. The second part of this thesis presents a methodology to control the crystal structure of Ag and Cu nanowires through direct electrodeposition techniques, which were tested directly as grown on the substrate to limit effects of pre-straining. Ag nanowires showed marked size-effects as well as two distinct modes of deformation which we attribute to the defects that arise during crystalline growth. We also show control of the surface microstructure in Cu nanowires which leads to strengths that are more than doubled compared to single crystalline Cu nanowires. Finally, we present support from classic crystal growth theory to justify that the observed plasticity in Ag and Cu nanowires is largely dependent on defects that are nucleated through changes in the growth environment.

Resumen
Metal-based nanoparticles (MNPs) are becoming increasingly common in commercial products. Release of these materials into the environment raises concerns about the potential risks they pose to aquatic life. Predicting these risks requires an understanding of MNPs' chemical transformations. In this study, arrays of immobilized MNPs fabricated by nanosphere lithography (NSL) were used to investigate environmental transformations of MNPs. Specifically, sulfidation of silver nanoparticles (Ag NPs) and dissolution of copper-based nanoparticles (Cu NPs) were investigated. Atomic force microscopy (AFM) and transmission electron microscopy were the primary analytical techniques for these investigations. Because the MNPs were immobilized on a solid surface, the samples were field deployable, environmentally relevant metal concentrations were maintained, and the confounding influence of MNP aggregation was eliminated. Ag NP samples were deployed in a full-scale wastewater treatment plant. Sulfidation occurred almost exclusively in anaerobic zones of the WWTP, where the initial sulfidation rate was 11-14 nm of Ag converted to Ag2S per day. Conversion to Ag2S was complete within 7-10 d. Dissolution rates of Cu-based NPs were measured in situ over a range of pH by flow-cell AFM. Based on the measured rates, CuO/Cu(OH)2 NPs dissolve completely within a matter of hours at any pH, metallic Cu NPs persist for a few hours to days, and CuxS NPs do not dissolve significantly over the time scales studied. Field deployment of samples in a freshwater stream confirmed these conclusions for a natural aquatic system. This research demonstrates that environmental transformations of MNPs will be a key factor in determining the ultimate form and concentration of NPs that aquatic organisms will be exposed to.

Resumen
La fabrication de composites constitués de collagène et d’hydroxyapatite a un grand intérêt dans la science des matériaux et la recherche biomédicale tout particulièrement pour des applications aux niveaux des tissus osseux. L’objectif est de synthétiser, à l’échelle nanométrique, un biomatériau à partir de ces 2 composantes d’une manière contrôlée dans le but de moduler ses propriétés physicochimiques, structurales et mécaniques. Ce projet de thèse met en évidence le rôle du collagène dans le mécanisme de minéralisation dans le but d’élaborer un nanomatériau biomimétique biomineralisé. Pour ce faire, plusieurs stratégies ont été mises en place: (i) assemblage de collagène et de cristaux d’hydroxyapatite préformés, (ii) minéralisation de l’hydroxyapatite par catalyse enzymatique (iii) élaboration de multicouches d’enzyme minéralisés par la méthode « couche-par-couche » dans un nanofilm ou nanotube en présence de collagène ou non. La caractérisation des différents matériaux nanostructurés minéralisés ainsi obtenus est réalisée par plusieurs techniques physicochimiques notamment la microscopie électronique à transmission (TEM) et à balayage (SEM), la microscopie à force atomique (AFM), la spectroscopie vibrationnelle (IR et Raman), le turbiscan, la microbalance à cristal de quartz (QCM-D) et la mesure de diffusion de la lumière (DLS)
The design of a composite based on collagen and hydroxyapatite crystals attractes a great interest in materials science and biomedical research particularly for bone tissue applications. The objective is to synthesize, at the nanoscale, a biomaterial from these two components in a controlled conditions in order to modulate its physicochemical, structural and mechanical properties. This thesis project highlights the role of collagen in the mineralization mechanism with the aim of developing a biomimetic biomineralized nanomaterial. To this end, several strategies have been suggested: (i) assembly of collagen with preformed hydroxyapatite crystals, (ii) mineralization of hydroxyapatite by enzymatic catalysis (iii) elaboration of mineralized enzyme-based multilayers by the "layer-by-layer" strategy to form a nanofilm or nanotube in the presence of collagen or not. The characterization of the various mineralized nanostructured materials obtained is performed by several physicochemical techniques including transmission electron microscopy (TEM) and scanning electron microscopy (SEM), atomic force microscopy (AFM), vibrational spectroscopy (IR and Raman), turbiscan, quartz crystal microbalance (QCM-D) and light scattering measurement (DLS)

Resumen
There is a growing interest among researchers on the interaction of living systems and biomaterials from the perspective of advanced biomedical engineering applications. Nanomaterials are employed in different biological applications (biosensing, molecular imaging, delivering drug particles, anticancer therapy etc.) because of their noble properties. Recently, boron nitride (BN NP) have attracted significant interest due to its superior chemical, physical and thermal properties and have found practical applications in fields like industrial tool manufacturing, electrical devices, photocatalysis and lubrication. However, studies to assess boron nitride for biomedical applications have been largely limited. This project aims at evaluating BN NP as a potential tool for advanced bioengineering applications. The study is conducted by focusing on four key aspects: nanomaterial characteristics, biocompatibility, uptake process and effect on biophysical properties. Simultaneously, Hydroxyapatite (HAP) was also assessed as a point of reference. Both BN NP and HAP were characterised based on their size, shape, surface charge and porosity to quantify the physical parameters of materials that dictate cellular response to nano-sized materials. The cytotoxicity of BN NP was extensively studied by conducting a number of biological assays. Overall, BN NP was found to be biocompatible within certain concentration range (0-50 μg/ml). Once the biocompatibility of BN NP was established, focus was placed on studying the uptake process and adopted mechanism. Cells were sectioned into thin slides (80 nm) after being cultured with nanomaterials and later imaged using transmission electron microscopy (TEM). Nanomaterials were observed inside cell cytoplasm, which confirmed successful internalisation of BN NP by human cells. The uptake process was extensively studied by analysing the microscopic images in a time dependent manner. The uptake mechanism of both BN NP and HAP was observed to be endocytosis. Finally, the effect of nanomaterial uptake on the biophysical properties of cells was investigated. While assessing nanomaterials, previous studies were largely limited to biological assay. However, in this study, it was hypothesised that, apart from biological consequences, nanomaterials uptake will also affect the physical properties of cells. Robust and accurate experimental techniques were developed to quantify the cell stiffness and adhesion property using Atomic force microscopy (AFM). The obtained results revealed increase in cell stiffness for BN NP treated cells (50 and 100μg/ml) and a significant decrease in adhesion property for HAP treated cells (100μg/ml). Together, these results demonstrated the effect of nanomaterial uptake on biophysical properties of cells and explained the underlying mechanism. This was an innovative way of studying the physical wellbeing of cells, which also contributed in the existing knowledge of nanomaterial toxicity. In summary, BN NP was evaluated in this study through an organised approach considering a number of key aspects. Collectively, this research develops a better understanding of the interaction between BN NP and human cells in in vitro condition and establishes a primary framework for nanomaterial assessment for biomedical use. The results validate BN NP's potential as a suitable biomedical engineering tool and emphasises the need for more research efforts in this field.

Resumen
AbstractIn this chapter, we will thoroughly discuss characterization techniques used to elucidate the exact structure and define properties of peptide-based nanomaterials. In particular we divide methods into: Quality control performance (mass spectroscopy and high-performance liquid chromatography. Spectroscopy (Fourier transform infrared spectroscopy, Raman spectroscopy, circular and linear dichroism, nuclear magnetic resonance and fluorescence spectroscopy). Microscopy (scanning and transmission electron microscopies, atomic force microscopy, optical and polarized light microscopy). Scattering (small angle X-ray and neutron scattering, X-ray diffraction). Bulk structures (mainly hydrogels) rheological characterization. The methodology is described for molecular structures, self-assembled nanostructures and aggregates, as well as hybrid, composite and/or conjugated nanomaterials and their bulk forms. Both common, as well as more exotic versions of all methods are presented in the context of peptide-based nanomaterials. Where utilized, examples of combinatorial use of techniques are demonstrated. Representative studies accompany the discussion and usefulness of all presented methods.

Resumen
The main objective of this work is to investigate the possibility of preparing bismuth telluride thin films using pulsed laser deposition. The effect of varying the deposition pressure, laser fluence, and the deposition temperature on the surface roughness, film composition, grain microstructure and electrical resistivity is analyzed using, scanning electron microscopy, atomic force microscopy, X-ray fluorescence, transmission electron microscopy, and four point probe measurements. It is demonstrated that relatively smooth films can be deposited at a laser flounce of 0.6 J/cm2 and using argon as a background gas at 10−1 mbar. On the other hand, resistivities as low as 2 mΩ.cm can be obtained by either depositing the film at 200°C, or by post-laser annealing films deposited at room temperature.

Resumen
Tin oxide thin films were grown by chemical vapor deposition (CVD) on glass substrates at atmospheric pressure (AP) and different temperatures of 400, 500 and 600 °C. The deposition times were also altered from 15 to 60 minutes with 15 minutes time intervals to investigate the effect of deposition time. A horizontal home-made reactor was used for the deposition from SnCl2 precursors with flowing pure oxygen at a rate 5 ccpm. The structure was analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM) and atomic force microscopy (AFM) facilities to reveal the deposition mechanisms and crystalline structures. Energy-dispersive spectroscopy (EDS) was conducted to understand the elemental surface composition of the thin films produced. It was detected that the morphology and the oxide structure were changed with deposition time and temperature. The optical and electrical properties were also studied to reveal a relationship between physical properties and production parameters of the resultant thin films.

Resumen
The forces affecting the ink particles attachment to the paper substrates control the inking and deinking processes. In deinking process, the detachment of ink particles represents a big challenge due to the presence of nano-sized ink particles which can not be separated by conventional means, therefore, it needs special type of treatment to adapt the chemistry of the surrounding solution to control the interfacial forces to separate the ink particle and make their detachment easier. Although studies have been made to correlate chemical structure of fatty alcohol ethoxylates with the efficiency of ink removal, there is still a significant lack of fundamental knowledge regarding the influence of the ethoxylate alcohol on the interaction forces between particulates involved in the deinking process. In this research, fundamental study of the effect of nano-sized ethoxylated alcohol molecules, which exhibits high potential for application in wastepaper deinking, on the ink particle detachment due to changes in the interfacial forces will be studied. In addition, the ability of ethoxylated alcohol to produce nano-size bubbles will be tested in terms of their effect on the ink particle removal. Furthermore, relationship between molecular structure of ethoxylated fatty alcohols (length and ratio of hydrophobic and hydrophilic parts) and ink (toner) will be characterized using atomic force microscopy (AFM) colloidal probe technique.

Resumen
Tin oxide has multiple technological applications including Li-ion batteries, gas sensors, optoelectronic devices, transparent conductors and solar cells. In this study tin dioxide (SnO2) thin films were deposited on glass substrates by RF sputtering process in the oxygen (O2) and argon (Ar) plasma medium. The deposition of the thin SnO2 films was carried out by RF sputtering from SnO2 targets. Before deposition the system was evacuated to 10−4 torr vacuum level and backfilled with Ar. The deposition of the nano structured thin SnO2 films have been performed at different gas pressures. The deposition of the SnO2 was both carried out at different pure argon gas pressures and argon/oxygen mediums with varying oxygen partial pressures. The effect of argon and argon/oxygen partial gas pressures on the grain structure and film thickness were analyzed in the resultant thin films. The deposited thin films both on glass and stainless steel substrates were characterized with scanning electron microscopy (SEM), X-ray diffractometry equipped with multi purpose attachment. The grain size of the deposited layer was determined by X-ray analysis. The Atomic Force Microscopy (AFM) technique was also conducted on the some selected coatings to reveal grain structure and growth behaviors.

Resumen
The properties and structure of nanoscale particles can vary widely from their bulk counterparts. In order to use nanoparticles effectively one must first have an understanding of their composition. In this study, Fe nanoparticles were grown on fused quartz substrates using a method that allows for varying particle size and surface coverage by altering the particle deposition time. The resulting particles were analyzed using x-ray photoelectron spectroscopy (XPS) in order to understand how nanoparticle composition evolves as a function of deposition time. In addition, atomic force microscopy (AFM) was used to correlate the changes in size and surface density of the Fe particles with the changes in the XPS spectra as deposition time was varied. Knowledge gained through this study will be used to optimize the growth of Fe nanoparticles for single-walled carbon nanotube (SWNT) synthesis.
