This book was released on 2002 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: We report a method for generating tri(ethylene glycol)-terminated-n-alkyltrichlorosiloxane monolayers on SiO2 surfaces. These chemisorbed films, with a thickness of ^2-3 nm, provide an oligo(ethylene glycol) surface that reduces the nonspecific adsorption of proteins and hydroxyl attachment sites for covalently immobilizing biomolecules to the substrate. These mono- molecular films were formed by adsorbing an acetoxy-tri(ethylene glycol)-terminated n-alkyl- trichlorosilane, CH3(C=O)O(CH2CH2O)3(CH2)11 SiCl3, onto glass and Si/SiO2 substrates, where the terminal acetate provided a protecting group for the hydroxyl functionality during self- assembly of the film. After formation of the monolayer, the acetate functionality was reduced chemically to form films exposing a covalently attached -(OCH2CH2)3OH terminus at a density of ^3x10(exp 14) molecules/sq cm. Protein adsorption studies verified that the films exhibited notable resistances against the non-specific adsorption of various proteins. Chemical modification of the -(OCH2CH2)3OH surface with protein. A provided a non-adsorbing surface for selective immobilization of immunoglobulins.
Book Synopsis Assemblies of Gold Nanoparticles at Liquid-Liquid Interfaces by : Evgeny Smirnov
Download or read book Assemblies of Gold Nanoparticles at Liquid-Liquid Interfaces written by Evgeny Smirnov and published by Springer. This book was released on 2018-04-19 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to various aspects of self-assembly of gold nanoparticles at liquid-liquid interfaces and investigation of their properties. It covers primarily two large fields: (i) self-assembly of nanoparticles and optical properties of these assemblies; and (ii) the role of nanoparticles in redox electrocatalysis at liquid-liquid interfaces. The first part aroused from a long-lasting idea to manipulate adsorption of nanoparticles at liquid-liquid with an external electric field to form 'smart' mirrors and/or filters. Therefore, Chapters 3 to 5 are dedicated to explore fundamental aspects of charged nanoparticles self-assembly and to investigate optical properties (extinction and reflectance) in a through manner. Novel tetrathiafulvalene (TTF)-assisted method leads to self-assembly of nanoparticles into cm-scale nanofilms or, so-called, metal liquid-like droplets (MeLLDs) with remarkable optical properties. The second part (Chapters 6 to 8) clarifies the role of nanoparticles in interfacial electron transfer reactions. They demonstrate how nanoparticles are charged and discharged upon equilibration of Fermi levels with redox couples in solution and how it can be used to perform HER and ORR. Finally, Chapter 9 gives a perspective outlook, including applications of suggested methods in fast, one-step preparation of colloidosomes, SERS substrates as well as pioneer studies on so-called Marangony-type shutters drive by the electric field.
Book Synopsis Low Density Triethoxysilane Self-assembled Monolayers and Its Stability Under Biological Media by : Nithya Subramanian
Download or read book Low Density Triethoxysilane Self-assembled Monolayers and Its Stability Under Biological Media written by Nithya Subramanian and published by . This book was released on 2015 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: A novel space-filling trialkoxysilane derivative was synthesized using a two-step strategy from commercially available starting materials to produce the precursor for the formation of low-density self-assembled monolayers. Self-assembled monolayers of the synthesized compound were prepared on three different substrates (Si/SiO$_{2}$, glass and ITO) and characterized using contact angle, ellipsometry and sum-frequency generation spectroscopy. Removal of the space-filling protecting group, (2-chlorophenyl)diphenyl methanol, yields a carboxyl-terminated surface. Correspondingly, the contact angle and film thickness decrease and the SFG spectra clearly indicate an increase in the gauche defect concentration characteristic of a low-density disordered monolayer. The biological stability of the prepared low-density monolayers compared to high-density monolayers of dodecyltriethoxysilane was studied under storage in water, phosphate buffer saline solution and calf serum for two weeks. The contact angle and thickness measurements show that there was no monolayer degradation during the storage time and the surfaces are more favorable for non-specific protein adsorption.

Download or read book Molecular Dynamics Study of Alkanethiolate Self-Assembled Monolayer Coated Gold Nanoparticle written by and published by . This book was released on 2007 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Through molecular simulations we have observed that the surface of gold nanoparticles become highly corrugated by the adsorption of alkanethiolate self assembled monolayers (SAMs). Furthermore, as the temperature is increased, the SAMs dissolve into the gold nanoparticle, creating a liquid mixture at temperatures much lower than the melting temperature of the gold nanoparticle. By analyzing the mechanical and chemical properties of gold nanoparticles at temperatures below the melting point of gold, with different SAM chain lengths and surface coverage properties, we have determined that the system is metastable. The model and computational results that provide support for this hypothesis are presented in this paper.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis addresses the fabrication and investigation of the optical response of gold nanoparticle arrays supported on insulating LiF(110) nanopatterned substrates. Motivated by the discovery of the intriguing effects that arise when electromagnetic radiation interacts with metallic nanostructures, the thesis focuses on the application of bottom-up approaches to the fabrication of extended-area plasmonic nanostructures, and the optimization of their optical response. By developing a sophisticated effective-medium model and comparing the experimental findings with model calculations, the author explores the role of the interparticle electromagnetic coupling and array dimensionality on the collective plasmonic behavior of the array, giving insights into the physical mechanisms governing the optical response.
Book Synopsis Surface Design and Controlled Assembly of Gold Nanoparticles Into Biodegradable Nanoclusters for Biomedical Imaging Applications by : Avinash Krishna Murthy
Download or read book Surface Design and Controlled Assembly of Gold Nanoparticles Into Biodegradable Nanoclusters for Biomedical Imaging Applications written by Avinash Krishna Murthy and published by . This book was released on 2013 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gold nanoparticles have received significant interest recently due to their utility in biomedical imaging and therapy. Nanoparticles which exhibit intense extinction in the near infrared (NIR) region, where blood and tissue absorb light weakly, are of great interest as contrast agents for biomedical imaging applications. While strong NIR extinction often requires sizes greater than ~20-30 nm, effective clearance from the body to avoid toxic accumulation necessitates sizes below ~6 nm. Moreover, effective clearance depends upon lack of adsorption of serum proteins in the bloodstream onto the particles. Herein, this conflict is addressed by assembling sub-5 nm gold nanoparticles into clusters with controlled size and morphology, in order to provide intense NIR extinction. Furthermore, the surfaces of the primary gold nanoparticles are designed such that the particles avoid the adsorption of any serum proteins. Binary ligand monolayers of anionic citrate and appropriate amounts of either cationic lysine or zwitterionic cysteine are synthesized to completely prevent serum protein adsorption from undiluted fetal bovine serum. A mechanism is proposed whereby the zwitterionic tips which are present on both the lysine and cysteine ligands limit the interactions between serum proteins and the "buried" charges on the nanoparticle surfaces. These primary nanoparticles are subsequently assembled into biodegradable nanoclusters via "quenched assembly", wherein nanoclusters are assembled and subsequently quenched by the adsorption of a biodegradable polymer on the cluster surface. The sizes of completely reversible "quenched equilibrium" nanoclusters formed from gold nanoparticles coated with a mixture of lysine and citrate are tuned from 20 nm to 40 nm, and nanocluster size is semi-quantitatively predicted by a free-energy model. Additional control over nanocluster size and extinction is demonstrated by adding NaCl, which is shown to decrease the polymer adsorption on the clusters and thus decrease polymer bridging interactions. This nanocluster formation platform is extended to nanospheres capped with citrate and the thiolated, zwitterionic cysteine ligand. A general paradigm is presented whereby the sizes and optical properties of biodegradable gold nanoclusters formed from nanospheres which do not adsorb any serum proteins are tuned via control over van der Waals, electrostatic, depletion, and polymer bridging colloidal interactions.

Book excerpt: The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.
