Available in PDF, EPUB and Kindle. Book excerpt: This dissertation covers three areas which I have worked on while pursuing my degree. The first chapter includes an introduction of the work presented. The second and third chapters are devoted to design and synthesis a new class of nanoparticles and the related Surface-enhanced Raman Spectroscopy (SERS) and Surface-enhanced Fluorescence (SEF) investigation. Chapter two reported a new strategy to prepare a class of SERS-active nanoparticles with reporters embedded between Au-core/Ag-shell. These core-shell nanoparticles can find use as SERS-tags for Raman-based assay with strong SERS signals and good stability. In chapter three, by adjusting the spacing and the dye position between the core and the shell, we have successfully observed the simultaneous SEF and SERS from our Au-core/Ag-shell nanoparticles. The combination of SEF and SERS onto single nanoparticles is highly desirable to improve the accuracy and sensitivity in detection applications, which has drawn increasing attention in recent years to study the two effects on the same nanostructures. The chapter four covers the applications of previously developed SERS-active nanomaterials. Using the metal core-shell nanoparticles as the SERS substrates, we have successfully performed quantitative SERS measurements of three different types of analytes by embedding an internal reference between the Au core and Ag shell. This strategy provides great flexibility in the choice of the internal references and analytes, and also allows quantitative SERS measurements of the analytes in the solution.

Available in PDF, EPUB and Kindle. Book excerpt: This groundbreaking book uniquely focuses on the exploration of the green synthesis of metal nanoparticles and their characterization and applications. Metal nanoparticles are the basic elements of nanotechnology as they are the primary source used in the design of nanostructured devices and materials. Nanomaterials can be manufactured either incidentally, with physical or chemical methods, or naturally; and the high demand for them has led to their large-scale production by various toxic solvents or high energy techniques. However, due to the growing awareness of environmental and safety issues, the use of clean, nontoxic and environment-friendly ways to synthesize metal nanoparticles has emerged out of necessity. The use of biological resources, such as microbes, plant parts, vegetable wastes, agricultural wastes, gums, etc., has grown to become an alternative way of synthesizing metal nanoparticles. This biogenic synthesis is green, environmentally friendly, cost-effective, and nontoxic. The current multi-authored book includes recent information and builds a database of bioreducing agents for various metal nanoparticles using different precursor systems. Green Metal Nanoparticles also highlights different simple, cost-effective, environment-friendly and easily scalable strategies, and includes parameters for controlling the size and shape of the materials developed from the various greener methods.

This book was released on 2019-05-10 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanoparticles exhibit a range of different properties when compared to bulk materials. Their high surface-area to volume ratio makes them particularly attractive for use as catalysts and recent years have seen an explosion of research in this area. The ability to fine-tune the size and structure of nanoparticles means that it is possible to design catalytic materials for improved activity or specificity. As catalysis is one of the key technologies for more sustainable production of both chemicals and energy, the past few years have seen increasing numbers of nanomaterials reported for these applications. Depending on the application, a number of different catalyst synthesis and optimization protocols can be used. This book provides comprehensive links between the design and fabrication method for nanoparticles and their catalytic performance (activity, selectivity and stability) in various applications. Presenting an introduction to the concept of catalyst design and recent developments in the preparation and characterisation of nanomaterials, followed by several chapters on the design of catalysts for specific applications, this book is a valuable resource for researchers working on catalytic reactions, industrial processes and nanomaterial applications.

Download or read book Synthesis and Characterization of Perm selective SERS active Silica coated Gold Nanospheres for the Direct Detection of Small Molecules written by Marie Carmelle Serviane Pierre-Bolivar and published by . This book was released on 2013 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: Above this value, however, uncontrolled nanoparticle aggregation occurred and large but irreproducible SERS signal intensities were monitored. Next, gold nanoparticles were encapsulated with varying silica shell thicknesses and purified using traditional centrifugation steps and/or column chromatography. Relative to the traditionally purified (i.e. centrifuged) samples, the SERS responses from small molecules using the column purified nanoparticle samples followed a well-known SERS distance-dependence model. Thus, surface chemistry cannot form more than a 2 nm thick layer on gold nanospheres if SERS applications were targeted. To overcome these challenges, gold nanospheres encapsulated with a thick silica shell were made SERS-active by etching the internal silica layer near the metal surface.

Download or read book Synthesis Characterization and Catalytic Application of Dendrimer stabilized Metal Nanoparticles written by Yunlong Gu and published by . This book was released on 2006 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first part of this work aims for a fundamental understanding of how PAMAM dendrimers function in controlling platinum nanoparticle size. We have carried out careful studies of Pt-PAMAM complexation and the nanoparticles produced by treatment with reducing agents. With respect to complexation, we have used UV-visible spectrophotometry, flame atomic absorption spectroscopy, and ion chromatography to elucidate the details of Pt complexation with PAMAM. The results show substantial amounts of non-complexed Pt present in the complex solution due to the slow, incomplete Pt ligand exchange reaction with PAMAM.
