Abstract:
Background. With the recent increase in antibiotic resistance to conventional antibiotics, gold nanoparticles, and medicinal plants, extracts present an interesting alternative. Objectives. This study aimed to synthesize, characterize, and evaluate Pyrenacantha grandiflora Baill extracts and gold nanoparticle conjugates against pathogenic bacteria. Methods. We synthesized gold nanoparticles by chemical and biological methods. The nanoparticles were characterized by the use of UV-visible spectrophotometry, followed by transmission electron microscopy (TEM) and energy-dispersive X-ray analysis (EDX). Gold nanoparticles were conjugated to plant extracts and analyzed with a Fourier-transform infrared spectroscope (FTIR). We determined the antimicrobial activity of the conjugates using well diffusion and the microdilution assays. Results. The UV–visible spectra of gold nanoparticles showed a synthesis peak at 530 nm. FTIR analysis indicated functional biomolecules that were associated with plant extract conjugated gold nanoparticles; the formation of C–H group and carbonyl (C=O) groups, –OH carbonyl, and C≡C groups were also observed. Biologically synthesized nanoparticles were star-shaped when observed by TEM with an average size of 11 nm. Gold nanoparticles synthesized with P. grandiflora water extracts showed the largest zone of inhibition (22 mm). When the gold nanoparticles synthesized by the biological method were conjugated with acetone extracts of P. grandiflora, MIC as low as 0.0063 mg/mL was observed against beta-lactamase producing K. pneumonia. The activity of acetone extracts was improved with chemically synthesized gold nanoparticles particularly when beta-lactamase producing E. coli and MRSA were used as test organisms. A synergistic effect was observed against all tested bacteria, except for MRSA when gold nanoparticles were conjugated with acetone extract. Conclusion. Overall, P. grandiflora tuber extracts conjugated with gold nanoparticles showed a very good antibacterial activity that improved both plant extract and gold nanoparticle’s individual activity.

Abstract:
With recent advances in nanotechnology, various nanomaterials have been used as drug carriers in molecular imaging for the treatment of cancer. The unique physiochemical properties and biocompatibility of gold nanoparticles have developed a breakthrough in molecular imaging, which allows exploration of gold nanoparticles in drug delivery for diagnostic purpose. The conventional gold nanoparticles synthetisation methods have limitations with chemical contaminations during the synthesisation process and the use of higher energy. Thus, various innovative approaches in gold nanoparticles synthetisation are under development. Recently, studies have been focused on the development of eco-friendly, non-toxic, cost-effective and simple gold nanoparticle synthesisation. The pulsed laser ablation in liquid (PLAL) technique is a versatile synthetic and convincing technique due to its high efficiency, eco-friendly and facile method to produce gold nanoparticle. Therefore, this study aimed to review the eco-friendly gold nanoparticle synthesisation method via the PLAL method and to characterise the gold nanoparticles properties for molecular imaging. This review paper provides new insight to understand the PLAL technique in producing gold nanoparticles and the PLAL parameters that affect gold nanoparticle properties to meet the desired needs in molecular imaging.

Abstract:
As a part of our ongoing investigation into the use of algae for gold nanoparticle synthesis, we screened the marine alga Kappaphycus alvarezii, to investigate its efficiency to reduce gold ions as well as the formation of gold nanoparticles. In the present work, we report the reaction condition of the alga K. alvarezii with aqueous gold ions for gold nanoparticle synthesis within the biomass extracellularly. The formation of gold nanoparticles was characterized by UV–Vis spectroscopy, Fourier transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD) method. Moreover, we have found that the reaction of gold ions with the K. alvarezii biomass under stationary conditions results in the rapid extracellular formation of gold nanoparticles of spherical morphology. The gold nanoparticles are not toxic to the cells that continued to grow after the biosynthesis of the gold nanoparticles.

Abstract:
Because of their unique properties, gold nanoparticles(NPs) show a wide range of applications such as surface-enhanced raman characteristics, biological sensing, biomedical and other fields. Different initial concentrations of Bull Serum Albumin(BSA) and egg white lysozyme respectively react with different size of gold nanoparticles. The condition of adsorption is determined by spectrometry method, then the area of protein with different molecular mass on the surface of a gold nanoparticle is calculated. The results show that the larger particle size of a gold nanoparticle is, the more protein the surface a gold nanoparticle adsorbs; the smaller the molecular mass of protein is, the more protein is adsorbed by gold nanoparticles surface.

Abstract:
Phytochelatins, the enzymatic products of phytochelatin synthase, play a principal role in protecting the plants from heavy metal and metalloid toxicity due to their ability to scavenge metal ions. In the present study, we investigated the capacity of soluble intracellular extracts from E. coli cells expressing R. tropici phytochelatin synthase to synthesize gold nanoparticle. We discovered that the reaction mediated by soluble extracts from the recombinant E. coli cells had a higher yield of gold nanoparticles, compared to that from the control cells. The compositional and morphological properties of the gold nanoparticles synthesized by the intracellular extracts from recombinant cells and control cells were similar. In addition, this extracellular nanoparticle synthesis method produced purer gold nanoparticles, avoiding the isolation of nanoparticles from cellular debris when whole cells are used to synthesize nanoparticles. Our results suggested that phytochelatins can improve the efficiency of gold nanoparticle synthesis mediated by bacterial soluble intracellular extracts, and the potential of extracellular nanoparticle synthesis platform for the production of nanoparticles in large quantity and pure form is worth further investigation.

Abstract:
Abstract The wide application of gold nanoparticles has attracted much attention to the development of research in gold nanoparticles. In this study, the gold nanoparticles were prepared by chemical reduction method using potassium tetrachloroaurate as the gold source and sodium borohydride as reducer agent. The formation of gold nanoparticles was confirmed by surface plasmon spectra in ultraviolet-visible spectroscopy at wavelength 507 nm. The capping process of gold nanoparticles was studied using two different charges of amino acids. The asparagine had used as uncharge amino acid and lysine as a positive charge amino acid. The redshift in surface plasmon spectra showed the aggregation of the gold nanoparticles after being capped with amino acids that indicates the surface modification. The amine and carboxylate group was present on the gold nanoparticle surface after being capped with amino acids. The zeta potential results indicate the lysine capped gold nanoparticles have slightly higher stability than the asparagine capped gold nanoparticles. These stability and surface modification of gold nanoparticles are expected to increase their utilization on biological and medical applications.

Abstract:
Colloidal gold nanoparticles have been researched and utilized in many technical applications. However, the conventionalmethods to produce polyethyleneglycol (PEG) immobilized gold nanoparticles have to take several steps, including residual solvent removing. In the study, we propose an idea green route to synthesize gold nanoparticles by using Stenotrophomonas maltophilia in a one-pot reaction. The relationship between Au precursor and S. maltophilia was evaluated systematically. After PEG-SH addition, the bacterial cell wall was broken down and the synthetic nanoparticles could be released into culture medium. Furthermore, we identified that the crystal structure of synthetic gold nanoparticle was face-center cubic and PEG-SH was immobilized on synthetic gold nanoparticle ideally. The size of Au-PEG-SH was smaller than 30 nm. These findings suggest that gold nanoparticle with PEG-SH modification could be prepared in an eco-friendly one-pot reaction through the metabolic activity of S. maltophilia.

Abstract:
The amalgamation of nanotechnology and biology has led to the development ofnew types of hybrid materials that are expected to produce major advances in areas such as materials science, therapeutics and diagnostics. One of the most promising developments is the use ofnanoparticles (NPs) as labels for the detection of analytes in biological assays. The aim of this research project was to prepare gold nanoparticle (GNP) labels for use in such assays. In chapter 1, the optical properties and the use of GNPs in homogeneous and heterogeneous colorimetric assays are reviewed. In chapter 2 a simple conjugation method is introduced that not only allows almost any biological molecule or hapten to be attached to GNPs but also allows the user to control or vary the mean number of molecules per particle. In this method a high molecular weight aminodextran polymer is functionalized with the molecule of choice and chemical attachment groups that are used to covalently anchor the polymer to the GNPs. This method was used to conjugate biotin and 1125 functionalized dextrans to GNPs. These functionalized dextrans were then used to investigate the conjugation procedure in more_detail. Results from GNP titrations and microbead assays demonstrate that the minimum amount of functionalized dextran required to prevent salt-induced flocculation ofthe GNPs (equivalence point) is the amount required to coat all of the GNPs and at this point there is no free functionalized dextran in solution. In chapter 3 the described method was used to conjugate different numbers DNP haptens to GNPs and then these labels were used in non-traditional reagent-limited lateral flow immunoassays. The number of molecules per GNP is varied by simply adjusting the stoichiometry of reagents in the dextran functionalization reaction. Controlling the number of molecules per particle can have important consequences on the sensitivity of a biological assay. Results showed that when the number of DNP molecules per particle decreased, there was an increase in the sensitivity of the assay. Furthermore when the results from these immunoassays were compared to those obtained from traditional reagent-limited lateral flow immunoassays, the nontraditional format proved to be over 50 % more sensitive. In chapter 4 the conjugation method was used to attach oligonucleotides to GNPs for use in a nucleic acids lateral flow (NALF) device. Although NALF devices are available commercially, detection is usually achieved with the use of antibodies or haptens which can be both problematic and expensive. In addition, many of these devices have issues with sensitivity and are often interfaced with complicated target amplification / purification protocols. In chapter 4 an antibody / hapten independent NALF device is described that can be used to detect the un-purified products from a simple polymerase chain reaction (PCR) amplification protocol. Using the developed NALF device it was possible to detect specific amplification products corresponding to ~1 attomole oftemplate molecules with the unaided eye.

Abstract:
Nanoelectrochemistry explores the differences in chemical behaviour at the nanoscale as compared to the macro-scale. This thesis is concerned with nanoelectrochemistry and aims to develop and apply novel experiments for the unambiguous identification of changed electrode kinetics at the nanoscale. This is challenging since electrochemical responses are controlled by diverse factors like enhanced mass transport and adsorption as well as electron transfer kinetics. A joint computational and experimental strategy is employed. Chapter 1, 2 and 3 cover essential introductory material and basic experimental details relevant to all experiment. Fuller descriptions and details are given in the following chapters as and when needed. Chapter 4 reports the development of an electrochemical characterization method, to achieve a fast and simple quantification of the average particle size and the number of nanoparticles deposited on a glassy carbon electrode. The method consists of surface area characterization by underpotential deposition of lead particles and the determination of the amount of gold from anodic stripping in HCl. This method is also proven to be effective by comparing the results with SEM measurements. Next, in chapter 5, a generic strategy combining computation and experimental approach is developed in order to study the electron transfer kinetics of gold nanoparticles. The modelling part considers the kinetics of the electrochemical process on the bulk materials for different regions in the electrode, that is, the substrate (glassy carbon) and the nanoparticles (gold). Comparison of experimental and theoretical results enables the detection of changes in the electrode kinetics at the nanoscale. This approach is applied into the electro-oxidations of nitrite and L-ascorbic acid for gold nanoparticles from 20 - 90 nm. In the former, analysing the system shows that no change in electron transfer kinetics is involved in the process, even though a decrease of the over-potential and an increase in the peak current are observed. But these changes reflect mass transport effects, not electrocatalysis. A case where an authentic enhanced electron transfer kinetic change occurs is shown for the ascorbic acid system. Finally, in chapter 6 , the above strategy is exploited further to apply a quantitative study of electron transfer kinetics for various sizes of gold nanoparticles in the oxygen reduction reaction system in sulphuric acid at 298 K. The latter is at the heart of energy transformation techniques (fuel cells, battery and so on). Compared with the electron transfer kinetics on macro gold electrodes, there is no change at gold nanoparticles from size 5 nm to 40 nm. However, in the presence of Pb(II), a strong enhancement of electron transfer kinetics is observed on 5 nm citrate capped gold nanoparticles for ORR. On the other hand, a significant decrease of electron transfer kinetics has been found for gold nanoparticles of size 2 nm for ORR. The latter observation of strong negative electrocatalysis is also observed for the hydrogen evolution reaction (HER). This represents the first report of such effects with the HER system. Overall the thesis has established a rigurous, theoretical basis for evaluating electrocatalysis in nanoparticulate system.

and the placement of the material. Hence, 3D printing can be an advantageous new method of constructing supercapacitors.In this thesis, the aim was to investigate how the different parameters of Electrohydrodynamic printing (EHD printing) will affect the spread of gold nanoparticles. The electrohydrodynamic printing method is a printing method that utilizes an electric field to cause droplet ejection from the nozzle. When the electric field exerts a force on the solution containing nanoparticles, it stretches the meniscus to a point where it becomes unstable and forms a droplet. EHD printing utilizes an electric field which gives the method a high spatial accuracy while being able to print droplets with within a separation distance of tens of nanometers.Different parameters were evaluated to achieve desired distribution of gold nanoparticles across a silicon wafer substrate. This thesis focuses on print speed, frequency, heat treatment and voltage, and how printing parameters affect the results. The results revealed a variation, while the printing patterns follow a trend. The best results achieved in this work came from a low nozzle-substrate voltage, high frequency, and high printing speed. The varying results could be brought on by variation in ink composition, the nozzle diameter, and the metal coating of the capillary, to name a few possible causes.Handledare:

Full text
Abstract:
This Thesis explores the properties and potential applications of 4-(dimethylamino)pyridine-capped gold (DMAP-Au) nanoparticles. The binding mode of the DMAP ligand to the gold surface was investigated in detail and the factors that make this substituted pyridine an effective protective ligand for gold nanoparticles were determined. DMAP-Au nanoparticle samples have a mean diameter between 5 and 6 nm and narrow size dispersity. DMAP is noncovalently bound to the nanoparticle surface via the endocyclic nitrogen. The positively charged nanoparticles are stable in aqueous solution over a wide pH range (5 to 12).
The interactions of DMAP-Au nanoparticles with the anionic polyelectrolytes poly(acrylate) and poly(styrene sulfonate) were investigated by following changes in the optical properties of the nanoparticles. The enhanced stability of the nanoparticles at low pH values observed in the presence of polyelectrolytes is attributed to the wrapping of the polyelectrolyte chains around the small nanoparticles. The study of the composition of the polyelectrolyte-coated nanoparticles reveals that the polyelectrolyte chains adsorb onto the DMAP protective monolayer rather than displace it at the nanoparticle surface.
The details of the interactions of the polyelectrolytes with a DMAP monolayer were further elucidated by using surface plasmon resonance (SPR) spectroscopy. This surface-sensitive technique allows the in situ study of the adsorption of the two polyelectrolytes on a 2D DMAP-modified gold surface and of their conformational changes as a function of pH. The results obtained correlate well with those of analogous 3D-systems. The polyelectrolyte chains are found to adsorb onto, and stabilize, the DMAP layer.
Finally, the use of DMAP-Au nanoparticles as a starting material in ligand exchange reactions was investigated. DMAP-Au nanoparticles prove to be excellent precursors to water- and organic-soluble nanoparticles. Relatively small amounts of incoming ligand are sufficient to fully replace the initial DMAP capping layer and the narrow size dispersity of the nanoparticles is maintained upon ligand exchange.

Abstract:
The concept of effective laser curing of nanoparticle suspensions (NPS) with a laser beam is presented in this paper. A toluene solvent is employed as the carrier of gold nanoparticles possessing a lower melting temperature than that of bulk gold. Using a modified drop-on-demand jetting system, the gold nanoparticle suspended solution is printed on a glass substrate and cured with laser irradiation. The laser energy coupling to the nanoparticles in conjunction with thermocapillary effects and the evaporation of the solvent are critical to the quality of the electrically conductive gold microlines. By employing a intensity-modulated double laser beam processing scheme, to optimize the curing process, it is demonstrated for the first time, that the gold nanoparticles could be sintered on a glass substrate to form a gold line of resistivity close to that of bulk gold. This is a noticeable result, compared to recently published microconductor manufacturing with nanoparticle suspensions with oven [1] or low power single laser beam [2] curing reporting resistivities four to five times higher than that of bulk gold. As a consequence, in addition to their scientific value, the current results demonstrate the potential of laser printing for use in the microelectronics manufacturing for the first time. It was also shown that the morphology of the gold line could be modified by appropriate design of the shape of the processing laser beam.
