Book Synopsis Gold Clusters, Colloids and Nanoparticles I by : D. Michael P. Mingos
Download or read book Gold Clusters, Colloids and Nanoparticles I written by D. Michael P. Mingos and published by Springer. This book was released on 2014-09-27 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: The series Structure and Bonding publishes critical reviews on topics of research concerned with chemical structure and bonding. The scope of the series spans the entire Periodic Table and addresses structure and bonding issues associated with all of the elements. It also focuses attention on new and developing areas of modern structural and theoretical chemistry such as nanostructures, molecular electronics, designed molecular solids, surfaces, metal clusters and supramolecular structures. Physical and spectroscopic techniques used to determine, examine and model structures fall within the purview of Structure and Bonding to the extent that the focus is on the scientific results obtained and not on specialist information concerning the techniques themselves. Issues associated with the development of bonding models and generalizations that illuminate the reactivity pathways and rates of chemical processes are also relevant. The individual volumes in the series are thematic. The goal of each volume is to give the reader, whether at a university or in industry, a comprehensive overview of an area where new insights are emerging that are of interest to a larger scientific audience. Thus 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 should be presented using selected examples to illustrate the principles discussed. A description of the physical basis of the experimental techniques that have been used to provide the primary data may also be appropriate, if it has not been covered in detail elsewhere. The coverage need not be exhaustive in data, but should rather be conceptual, concentrating on the new principles being developed that will allow the reader, who is not a specialist in the area covered, to understand the data presented. Discussion of possible future research directions in the area is welcomed. Review articles for the individual volumes are invited by the volume editors. Readership: research scientists at universities or in industry, graduate students Special offer For all customers who have a standing order to the print version of Structure and Bonding, we offer free access to the electronic volumes of the Series published in the current year via SpringerLink.

Book Synopsis Effective Medium Theory of DNA-linked Gold Nanoparticle Aggregates: Effect of Aggregate Shape by : Anne A. Lazarides
Download or read book Effective Medium Theory of DNA-linked Gold Nanoparticle Aggregates: Effect of Aggregate Shape written by Anne A. Lazarides and published by . This book was released on 2001 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present a dynamical effective medium theory (EMT) of the dielectric properties of nanoparticle aggregates formed from DNA-linked gold nanoparticles. Experimental measurements show that such aggregates have reduced UV extinction and plasmon bands that are considerably red-shifted and broadened relative to the plasmon absorption feature observed in spectra of dispersed colloid. The EMT, which can be used to reproduce the observed spectral changes, is tested by comparing aggregate spectra calculated using the EMT dielectric function with spectra from explicit coupled particle calculations, and good agreement is found. The EMT dielectric function is used as well in discrete dipole calculations to calculate extinction spectra for a variety of aggregate shapes not amenable to analytic solution, and the sensitivity of the spectra to aggregate shape is examined. We find that the spectra are only weakly sensitive to aggregate shape, and conclude that, when calculating extinction of the DNA-linked aggregates for comparison with experiment, spherical shapes can be assumed.

Book Synopsis Nanobioelectronics - for Electronics, Biology, and Medicine by : Andreas Offenhäusser
Download or read book Nanobioelectronics - for Electronics, Biology, and Medicine written by Andreas Offenhäusser and published by Springer Science & Business Media. This book was released on 2009-03-15 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: The combination of biological elements with electronics is of great interest for many research areas. Inspired by biological signal processes, scientists and engineers are exploring ways of manipulating, assembling, and applying biomolecules and cells on integrated circuits, joining biology with electronic devices. The overall goal is to create bioelectronic devices for biosensing, drug discovery, and curing diseases, but also to build new electronic systems based on biologically inspired concepts. This research area called bioelectronics requires a broad interdisciplinary and transdisciplinary approach to biology and material science. Even though at the frontier of life science and material science, bioelectronics has achieved in the last years many objectives of scientific and industrial relevance, including aspects of electronics and biotechnology. Although the first steps in this field combined biological and electronic units for sensor applications (e. g. , glucose oxidase on an oxygen electrode), we see now many applications in the fields of genomics, proteomics, and celomics as well as electronics. This approach challenges both the researcher and the student to learn and think outside of their zones of comfort and training. Today, one can fabricate electrically active structures that are commensurate in size with biomolecules. The advancement of nanotechnology has influenced bioelectronics to a large extent.

Book Synopsis Anisotropies in Discrete DNA-assembled Gold Nanoparticle Structures by : Jessica Marie Smith
Download or read book Anisotropies in Discrete DNA-assembled Gold Nanoparticle Structures written by Jessica Marie Smith and published by . This book was released on 2014 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plasmon rulers consisting of optically coupled metal nanoparticles linked by biological macromolecules have provided a tool for bio-imaging and enzymology that is non-bleaching, non-blinking, and biocompatible. A pair of plasmonic nanoparticles couple when they are in spatial proximity, resulting in spectral shifts and increased scattering intensity. Previ- ous research has developed synthetic techniques for precisely assembling gold nanoparticles using DNA. Two self-assembled plasmonic nanoparticles have been shown to be an enzyme- responsive material in one-dimension. In order to visualize the subtle conformational changes ubiquitous in biological systems, three-dimensional, anisotropic nanoparticle assemblies are required. This dissertation reports two examples of next-generation plasmon rulers. DNA-assembled dimers of gold nanorods can act as a three-dimensional plasmon ruler only if the relative orientation of the particles can be controlled. By tuning the conditions of electrophoretic separation and the DNA structure, a sample of gold nanorod dimers that are attached side-by-side can be isolated from those attached end-to-end. TEM characterization of these oriented dimers shows a statistically significant deviation from randomly oriented nanorod pairs. Because of the high yield of oriented nanorod pairs, this colloidal sample can serve as an ensemble biosensor. A three-dimensional plasmon ruler can also be synthesized by increasing the complexity of the underlying DNA structure. Four DNA strands, each attached to a gold nanoparticle, hybridize such that each strand folds into one face of a chiral pyramid. The sequence of the four strands was designed to maximize the yield of one enantiomer based on tertiary structure of the double helices. This structure is a circular dichroism-based nanoparticle ruler for subtle biological events, such as the extension of DNA by a DNA-binding protein. Additionally, the DNA-assembled gold nanoparticle system was characterized by state- of-the-art electron microscopy. A method called individual particle electron tomography can be used to image single macromolecules. By tuning the parameters of the negative stain, the transmission electron microscope (TEM), and the buffer conditions, this method has been extended for the reconstruction of a 3D density map of an individual DNA double helix labeled by two nanoparticles. Previous work on cryo-EM imaging of DNA nanostructures without gold nanoparticles has relied on averaging many images together to create a com- posite density map. This work represents an electron microscopy constructed density map of a DNA double helix. Liquid-phase TEM can probe and visualize dynamic events with structural or functional details at the nanoscale in a liquid medium. The grapheme liquid cell was adopted to seal an aqueous sample solution containing DNA-assembled gold nanoparticle dimers against the high vacuum in TEM. Quantitative analysis of collected real time nanocrystal trajec- tories reveals the fidelity of the DNA in the presence of the electron beam as well as the reconstruction of the 3D configuration and motion of the nanostructure.
Download or read book Nanoporous Gold written by Arne Wittstock and published by Royal Society of Chemistry. This book was released on 2012-03-28 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-surface-area materials have recently attracted significant interest due to potential applications in various fields such as electrochemistry and catalysis, gas-phase catalysis, optics, sensors and actuators, energy harvesting and storage. In contrast to classical materials the properties of high-surface-area materials are no longer determined by their bulk, but by their nanoscale architecture. Nanoporous gold (np-Au) represents the fascinating class of mesoporous metals that have been intensively investigated in recent years. The current interest and the increasing number of scientific publications show that np-Au by itself is an outstanding nano-material that justifies a book devoted to all aspects of its properties and applications. The resulting publication is a discussion of this unique nano-material and is an accessible and comprehensive introduction to the field. The book provides a broad, multi-disciplinary platform to learn more about the properties of nanoporous gold from an inter-disciplinary perspective. It starts with an introduction and overview of state-of-the-art applications and techniques characterizing this material and its applications. It then covers the progress in research within the last years. The chapters are in-depth overviews written by the world's leading scientists in the particular field. Each chapter covers one technique or application so that the reader can easily target their favoured topic and will get the latest and state-of-the-art information in the field.
