Abstract Since 2014, black phosphorus (BP) has gained more and more attention because of its unique physicochemical properties. In particular, with unique electrical, optical, and biodegradable performances, BP may serve as an alternative for other two-dimensional nanomaterials (2DNMs) in biomedical applications. However, the practical application of BP in the biomedical field still faces great challenges. In this article, we focus on the various synthesis methods of BP, including the exfoliation method, chemical vapor deposition (CVD) method, and wet-chemical self-assembly method, and recent advances of BP in biomedical fields, such as biosensing, imaging, drug delivery, phototherapy, and bioactive phospho-therapy are highlighted. Finally, the current challenges of BP in biomedical applications are briefly discussed. It is believed that this article will provide effective scientific support for the development and application of BP.

Streszczenie:

By interconnecting nanomachines and forming nanonetworks, the capacities of single nanomachines are expected to be enhanced, as the ensuing information exchange will allow them to cooperate towards a common goal. Nowadays, systems normally use electromagnetic signals to encode, send and receive information, however, in a novel communication paradigm, molecular transceivers, channel models or protocols use molecules. This article presents the current developments in nanomachines along with their future architecture to better understand nanonetwork scenarios in biomedical applications. Furthermore, to highlight the communication needs between nanomachines, two applications for nanonetworks are also presented: i) a new networking paradigm, called the Internet of NanoThings, that allows nanoscale devices to interconnect with existing communication networks, and ii) Molecular Communication, where the propagation of chemical compounds like drug particles, carry out the information exchange.

Streszczenie:

Graphene-based materials are being widely explored for a range of biomedical applications, from targeted drug delivery to biosensing, bioimaging and use for antibacterial treatments, to name but a few. In many such applications, it is not graphene itself that is used as the active agent, but one of its chemically functionalized forms. The type of chemical species used for functionalization will play a key role in determining the utility of any graphene-based device in any particular biomedical application, because this determines to a large part its physical, chemical, electrical and optical interactions. However, other factors will also be important in determining the eventual uptake of graphene-based biomedical technologies, in particular the ease and cost of manufacture of proposed device and system designs. In this work, we describe three novel routes for the chemical functionalization of graphene using oxygen, iron chloride and fluorine. We also introduce novel in situ methods for controlling and patterning such functionalization on the micro- and nanoscales. Our approaches are readily transferable to large-scale manufacturing, potentially paving the way for the eventual cost-effective production of functionalized graphene-based materials, devices and systems for a range of important biomedical applications.

Streszczenie:

Aromatic and aliphatic diacid chlorides were used to condense naturally occurring diamino acids and their esterified derivatives. It was anticipated the resulting functional polyamides would biodegrade to physiologically acceptable compounds and show pH dependant solubility could be used for biomedical applications ranging from enteric coatings to hydrosoluble drug delivery vehicles capable of targeting areas of low physiological pH. With these applications in mind the polymers were characterised by infra red spectroscopy, gel permeation chromatography and in the case of aqueous soluble polymers by potentiometric titration. Thin films of poly (lysine ethyl ester isophthalamide) plasticised with poly (caprolactone) were cast from DMSO/chloroform solutions and their mechanical properties measured on a Hounsfield Hti tensiometer. Interfacial synthesis was investigated as a synthetic route for the production of linear functional polyamides. High molecular weight polymer was obtained only when esterified diamino acids were condensed with aromatic diacid chlorides. The method was unsuitable for the production of copolymers of free and esterified amino acids with a diacid chloride. A novel miscible mixed solvent single phase reaction was investigated for production of copolymers of esterified and non-esterified amino acids with diacid chlorides. Aliphatic diacid chlorides were unsuitable for condensing diamino acids using this technique because of high rates of hydrolysis. The technique gave high molecular weight homopolymers from esterified diamino acids and aromatic diacid chlorides.

Functional polymeric thin films are often stratified with nanometer level structure and distinct purposes for each layer. These nanostructured polymeric materials are useful in a wide variety of applications including drug delivery, tissue engineering, controlling condensation and polymeric batteries; all of which will be discussed in this work. The first area of my thesis will detail the use of C₆₀ cluster-ion depth profiling X-ray Photoelectron Spectroscopy (XPS) to fundamentally understand how thin film structure and function relate. This method has the unique capability to determine the atomic composition and chemical state of polymeric thin films with <10nm nanometer depth resolution without any chemical labeling or modification. Using this technique, I probed the nanostructure of functional thin films to quantify the interlayer diffusion of the biopolymer chitosan as well as demonstrate methods to stop this diffusion. I also explored the role of interlayer diffusion in the design of hydrophobic yet antifogging 'zwitter-wettable' surfaces. Additionally, I probed the lithium triflate salt distribution in solid block copolymer battery electrolytes (PS-b-POEM) to understand the lithium-ion distribution within the POEM block. In the second area of my thesis, I show how the nanostructure of materials control the function of polymeric particles in vitro and in vivo. One example is a 'Cellular Backpack' which is a flat, anisotropic, stratified polymeric particle that is hundreds of nanometers thick and microns wide. In partnership with the Mitragotri group at UCSB, we show that cellular backpacks are phagocytosis resistant, and when attached to a cell, the cell maintains native functions. These capabilities uniquely position backpacks for cell-mediated therapeutic delivery and we show in vivo that immune cells attached to backpacks maintain their ability to home to sites of inflammation. In addition, we have designed polymeric microtubes that can control their orientation on the surface of living cells. Inspired by chemically non-uniform Janus particles, we designed tube-shaped, chemically non-uniform microparticles with cell-adhesive ligands on the ends of the tubes and a cell-resistant surface on the sides. Our results show that by altering the surface chemistry on the end versus the side, we can control the orientation of tubes on living cells. This advance opens the capability to control phagocytosis and design cellular materials from the bottom up.

Switchable oligopeptides, able to expose of conceal biomolecules on a surface, upon the application of an electrical potential, represent a versatile tool for the development of novel devices, presenting potential biomedical applications. Recently, several studies have demonstrated the applicability of smart devices for the control of protein binding and cellular response. In this work; a detailed analysis of the steric requirements necessary to develop a mixed oligopeptide Self-Assembled Monolayer (SAM) presenting an optimum switching ability will be described. The influence of both the SAM components surface ratio and the switching unit length on the mixed SAMs switching performance will be investigated. The findings of this investigation will be used to develop, for the first time, a platform, based on electrically switchable oligopeptides, able to control the interaction between an antigen and its relative antibody. The influence of the biological medium on the oligopeptide switching ability will also be investigated. Finally, an orthogonal functionalisation strategy, will be investigated in detail, together with a new platform able to promote human sperm cells adhesion. The results of this research thesis will also represent the first building blocks towards the development of glass-gold rnicropattemed surfaces able to control the calcium signalling in human sperm cells, presenting potential applications in the improvement of in-vitro fertilisation (NF) treatments success rates.

Streszczenie:

Ion sensitive field effect transistors (ISFETs) have long been used as analogue chemical sensors particularly for biomedical applications. However, there are some applications where a "yes" / "no" type answer regarding pH change is sufficient. For example, in DNA sequencing the question is whether a chain extension reaction took place or not. Detecting this at the sensing point reduces the sensing process to pH change threshold detection. It eliminates the need for analogue to digital conversion and facilitates an all digital sensory system. This thesis presents Novel Floating Gate ISFET based Chemical Inverters that were created with semiconductor based biomedical applications in mind. It starts by allowing two ISFETs to share the same ion sensing membrane and a common floating gate. Arranging them in a simple FG inverter configuration, their switching may be triggered by either the reference voltage or chemical pH change. In order to enhance its input noise immunity, a chemical Schmitt Trigger is presented. Using ISFETs for the detection of minute pH changes have been a challenge. A simple method to locally scale input referred chemical signal at the ISFET's floating gate is presented. It is based on using the ratio of capacitive coupling to the floating gate. The chemical signal is coupled via the passivation capacitance (Cpass) while an electrical input (V2) is coupled via a poly capacitance (C2). V2 sees the chemical signal with a scaling of Cpass/C2, which can be designed. Finally, ISFETs suffer from initial trapped charges that cause mismatch between devices in the same die. A fast matching method is presented here, that can be used to hugely reduce mismatch of arrays of FG devices. It is based on using indirect bidirectional tunnelling. Two tunnelling structures are added to each ISFET's FG, one adds electrons to it while the other removes them. It is possible to match all ISFETs' initial FG voltages to a point where both tunnelling currents reach equilibrium.

Streszczenie:

This thesis presents the design and characterization of a novel pulsed miniature capacitively-coupled Atmospheric Pressure Glow Discharge Torch (APGD- t) aimed at localized biomedical applications. Amplitude modulation of the 13.56 MHz carrier signal allows to continuously vary the power level applied to the APGD-t. Typically, the APGD-t produces a plasma jet with a 150-500 μm diameter and ≈2.5 mm length. Helium (He) is the plasma-forming gas with a flow rate ranging from 0.5 to 1.5 slm. The use of a small capillary electrode enhances the electric field, lowering the breakdown voltage (typically 220 Vpk-to-0) and allows the injection of small amounts (0-50 sccm) of a source of reactive species (O2) downstream of the plasma-forming region, in the plasma afterglow. The O2 is electronically dissociated in the plasma afterglow to create atomic oxygen (O) with no effect on the electrical properties. A ratio of 0.3% v/v, O2/He generates a maximum in O production.
Careful electrical probe measurements and circuit analyses reveal the strong effect of commercial passive voltage probes on the total load impedance of the APGD-t circuit. The larger the probe capacitance and cable length, the larger the component of the phase angle between the load voltage and circuit current signals induced by the probe. The calibration of the phase angles induced by the voltage probes allows to estimate that a resistive power of ~0.24-1 W is dissipated in the APGD- t under nominal operating conditions.
The gas kinetic and atomic He excitation temperatures, and the electron density near the APGD-t nozzle exit are estimated at ≈323 K, ≈1914 K and ≈1011 cm-3, respectively. This confirms that the APGD-t plasma jet near the nozzle exit is in a non-thermal equilibrium state. The emission spectroscopy study reveals the entrainment of air molecules (N2, O2 and H2O) in the plasma jet, and that their excitation by the plasma creates new reactive species (O and OH). A preliminary survey of the chemical reactions taking place in the plasma afterglow reveals that metastable He as well as OH, O, O2(a1Δg), O2(b1Σg+), N2, N2+ and O3 are plasma species that can reach and react with organic or biological surfaces located a few mm downstream of the APGD-t nozzle exit. This thesis demonstrates that the APGD-t is a promising tool for localized biomedical applications.

Hydrocolloid materials have been used for some time in the fields of regenerative medicine and drug delivery. Despite a significant body of work, to date the majority of research in the area has focused on relatively simple compositions and microstructures. In comparison, the food industry has long used refined and often subtle methods to structure and thereby tailor the release and handling properties of a vast range of similar materials. In this thesis, a range of processing methodologies has been used to generate novel materials intended for use in the regenerative medicine and drug delivery using gellan and kappa carrageenan. The thesis demonstrates how even small changes in process conditions can result in significant changes in the way a material handles and may deliver therapeutic molecules. This thesis has demonstrated that gellan can be used to form robust quiescent structures, as well as shear thinning fluid materials by changing the processing and formulation. Furthermore, it was demonstrated that it was possible to generate a novel cell delivery device by the hydration of kappa carrageenan in warm biomedical buffers. Overall this thesis demonstrates the range and complexity of structures that can be produced using the relatively small number of polymers.

The main objective of this dissertation is the synthesis and study of modified surface systems for the development of bioactive platforms and their use in specific biotechnological and biomedical applications. This work has led to various biological template development projects; all in attempts to provide new surfaces and probes in nanotechnology. These projects focus mainly on protein modified surface platforms, liposome based spherical platforms, and carbon nanotubes based magnetic platforms. The planar platforms include gold, silicon and aluminum oxide surfaces. Spherical surfaces such as liposomes and nanoparticles were also studied, and finally, surface modification was extended to carbon nanotubes and magnetic nanoparticles. In this dissertation, the planar surface work focuses on demonstrating the behavior of proteins at interfaces in terms of conformation, stability and activity (e.g., of avidin, trypsin and antibodies) using fluorescence microscopy. Different ligands were attached chemically on the surfaces to incorporate hydrophobic hydrophilic and charged characteristics. A chelating agent (iminodiacetic acid, IDA), an affinity ligand (biotin), and reactive groups (amino and carboxylic groups) were covalently incorporated onto the surfaces. Proteins including myoglobin, cytochrome C, avidin, trypsin and immunoglobulin G (IgG) were used in this study. The results show that proteins and ligands were successfully attached to different surfaces. Protein adsorption studies illustrate activity decrease by using fluorescence intensity. After attachment on hydrophobic functionalized surfaces. Along the same line, experiments were conducted on the comparison of silicon dioxide and gold-coated surfaces with immobilized enzymes, small molecules, and polymers for potential use as biosensors. Silicon dioxide wafers were prepared via silanization with 3-aminopropyl triethoxysilane (APTES) followed by glutaraldehyde activation and, finally, protein and/or small ligand attachment. Gold-coated surfaces were utilized for immobilizations using 16-mercaptohexadecanoic acid (MHA) which forms self-assembled monolayers (SAMs) on gold surfaces followed by covalently attachment of proteins. The activity of trypsin immobilized onto these surfaces was also measured. The silicon dioxide wafers when modified first with NH₂-PEG-NH₂ allowed for trypsin a relatively higher activity with about 11% greater activity than when attached on gold surfaces and 84% higher activity than on bare silicon surfaces. Furthermore, the bimolecular silicon dioxide surfaces were shown to be much more stable than the gold surfaces. The silicon dioxide surfaces with an immobilized reversible inhibitor, p-aminobenzamidine (PAB), show to very effectively bind proteins from solution compared to gold surfaces. Liposome were studied because their versatility and vast implications in bio-sensing and drug-delivery potential. In this work, liposomes were prepared with the phospholipids 1,2-dimyristoyl-sn-glycero-3-phosphoethanolamine (DMPE), 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC) and cholesterol. The amino groups of DMPE were then modified with ligands that included iminodiacetic acid (IDA), and PEG. These functionalized liposomes were used to prepare dispersed gold “nano-dots” on their surface. These novel functional liposomes, with chelating ligands and polymers can be used to bind biomolecules and active compounds (nanoparticles of gold, quantum dots, drugs) with long stability. The results show that we can successfully manufacture functional liposomes and form gold nanoshells on their external surface. These two types of systems can be used as drug delivery, and as imaging systems. Their characterization and potential use in biomedical applications as contrast agents seems quite promising once complexity and stability of these gold nanoshells is elucidated. The modification and preparation of functional-carbon nanotubes was investigated with the chemical hetero-junction analysis between magnetic nanoparticles coated poly-acrylic acid (PAA) and multi-wall carbon nanotubes (MWCNTs). Magnetic nanoparticles were covalently attached to open-ended nanotubes. Initial evidence suggests that short functionalized multi-wall nanotubes can be continuously connected at their terminal ends for build-up of relatively large nanostructures based on serial configurations. It is shown that magnetic carbon nanotubes systems exhibit defined arrangements due to the influence of magnetic fields. Indeed, linear arrays of carbon nanotubes inter-connected through magnetic nanoparticles were prone to be manipulated in the presence of a magnet device. A potential application of these magnetic nanostructures was shown by successfully manipulating agarose beads in buffer solution as a model system. These results suggest that the use of continuously connected magnetic nanostructures with non-modified sidewall surfaces will find potential applications in the areas of bio-sensing, force transduction and cancer screening-manipulation among others.

Mestrado em Ciência e Engenharia de Materiais
Calcium phosphate-based materials, in particular hydroxyapatite-based ones,are among the most important materials for biomedical applications (bone graftsubstitutes, drug delivery systems, etc.). Owing to their compositional similaritywith respect to hard tissues, these materials show superior bioactive,osteoconductive, cell seeding and growth environment properties. Additionally,their capability to adsorb biological important substances like proteins, drugs,etc. makes them interesting materials to be used as drug delivery systems. Several studies on the effects of morphological aspects like particle size,shape, pore size and pore volume on the biological behaviour of calciumphosphate-based materials have shown that the properties of these materialscannot be considered merely on compositional aspects, but the role ofmorphological issues must also be taken into consideration. In the present work, calcium phosphate particles with a wide range of sizeswere produced by precipitation in calcium/citrate/phosphate solutions. It wasobserved that the manipulation of experimental conditions, namely the citrate-calcium ratio (Cit/Ca) and the pH of the solution, allowed to producehydroxyapatite particles either as nanosized particles, either as micrometricsized aggregates with particular shapes. The different sizes and shapes wereanalyzed in the framework of nucleation and growth phenomena and henceattributed to the development of different particle surface charge conditionsrelated to the adsorption of differently charged citrate species. The study of the preparation of calcium phosphate porous granules by spraydrying the suspensions of the various precipitated hydroxyapatite particles wasalso undertaken in the present work. The obtained results showed that thedifferent morphologies of the suspended hydroxyapatite particles havesignificant effects on the spray dried granules’ morphology and microstructure,thus accounting for different pore size and pore size distributions. Moreover,the study of the spray dried granules heat treatment demonstrated that not onlythe granules’porosity may be further modified but also its crystal phasecomposition. In view of the potential applications of the porous materialsprepared in this work such as drug, growth factors and stem cells carriers or aspromoter of cell adhesion, the present study points out to a wide range ofpossibilities for producing calcium phosphate porous granules with a differentschedule of morphological characteristics.
Os materiais fosfo-cálcicos, particularmente aqueles à base de hidroxiapatite, são dos mais importantes para aplicações biomédicas, como por exemplo, a substituição óssea e os sistemas de libertação controlada de fármacos. Este facto deve-se principalmente à semelhança da sua composição com a parte inorgânica do tecido ósseo. É esta semelhança que está na origem dasnotáveis propriedades biológicas destes materiais, tais como: excelente bioactividade e osteoconductividade. Por outro lado, estes materiais possuem ainda a capacidade de adsorver substâncias com interesse biológico,(proteínas, drogas, etc.) o que os torna interessantes como sistemas delibertação controlada de fármacos. No entanto, alguns estudos têmdemonstrado que o comportamento biológico dos materiais fosfo-cálcicos não depende apenas da sua composição mas também de aspectos morfológicos, tais como: tamanho e forma departícula, tamanho e volume de poro, etc. No presente trabalho produziram-se, por precipitação a partir de soluções de cálcio/citrato/fosfato, partículas de fosfato de cálcio com uma grandediversidade de tamanhos. Observou-se que a manipulação das condiçõesexperimentais, nomeadamente a razão citrato/cálcio (Cit/Ca) e o pH dasolução, possibilitaram a produção de partículas de hidroxiapatite, quer na forma de partículas com tamanhos nanométricos, quer na forma de agregados micrométricos com formas peculiares. A variedade de tamanhos e formas daspartículas produzidas foi analisado no contexto dos fenómenos de nucleação e crescimento, tendo sido atribuídaao desenvolvimento de diferentes condições de carga superficial devidas à adsorção de espécies iónicas de citrato com diferentes cargas. No presente trabalho desenvolveu-se também o estudo da preparação de grânulos porosos de fosfato de cálcio, por atomização de suspensões de partículas de hidroxiapatite com diferentes morfologias. Os resultados obtidosmostraram que a utilização de partículas com diferentes morfologias influenciasignificativamente a morfologia e microestrutura dos grânulos atomizados, oque origina grânulos com diferentes tamanhos e distribuição de tamanho deporos. Além disso, demonstrou-se que o tratamento térmico permite modificar não só a porosidade dos grânulos, mas também a sua composição cristalina.Tendo em vista as potenciais aplicações dos materiais porosos preparadosneste trabalho, tais como sistemas de libertação controlada de fármacos,factores de crescimento e de células estaminais ou como promotores daadesão de células, o presente trabalho sugere a possibilidade de produção de grânulos de fosfato de cálcio com uma vasta multiplicidade de características morfológicas.

Streszczenie:

In this investigation, we synthesize FeNi alloy magnetic nanoparticles (MNPs) by using both chemical precipitation and combustion methods. The FeNi MNPs prepared by combustion method have a rather high saturation magnetization Ms of ∼180 emu/g and a coercivity field Hc of near zero. The functionalized FeNi MNPs which were coated with biocompatible polyethyleneimine (PEI) polymer have also been synthesized. We demonstrated that the PEI coated FeNi MNPs can enter the mammalian cells in vitro and can be used as a magnetic resonance imagine (MRI) contrast agent. The results demonstrated that FeNi MNPs potentially could be applied in the biomedical field. To prepare a higher quality and well controlled Fe-Ni MNPs, we also developed a thermal reflux chemical precipitation method to synthesize FeNi3 alloy MNPs. The precursor chemicals of Fe(acac)3 and Ni(acac)2 in a molecular ratio of 1:3 reacted in octyl ether solvent at the boiling point of solvent (∼300°C) by the thermal reflux process. The 1,2-hexadecandiol and tri-n-octylphosphine oxide (TOPO) were used as reducer and surfactant, respectively. The chemically precipitated FeNi3 MNPs are well dispensed and have well-controlled particle sizes around 10–20 nm with a very narrow size distribution (± 1.2 nm). The highly monodispersive FeNi3 NPs present good uniformity in particle shape and crystallinity on particle surfaces. The MNPs exhibit well soft magnetism with saturation magnetization of ∼61 emu/g and Hc ∼ 0. The functionalized magnetic beads with biocompatible polymer coated on MNPs are also generated completed for biomedical applications.

Streszczenie:

Mini centrifuges are compact benchtop centrifuges designed to meet the centrifugation needs of laboratories with limited space. Primarily used for quick spin-downs, they are particularly suitable for microfuge and PCR tubes. Operating on the principle of sedimentation, mini centrifuges separate molecular lab samples based on density. They find applications in various fields like environmental, chemical, molecular biology, and biomedical research, including mixing PCR master mix and microfiltration. Despite their advantages of space efficiency and ease of use, they are not well-suited for high-output labs due to their small to medium output yield.
