Available in PDF, EPUB and Kindle. Book excerpt: There is a growing interest in the use of nanoparticles modified with DNAs, viruses, peptides and proteins for the rational design of nanostructured functional materials and their use in biosensor applications. The challenge is to control the organization of biomolecules on nanoparticles while retaining their biological activity as potential chemical and gene therapeutics. These noble metal nanoparticles/biomolecules conjugates have specific properties and therefore they are attractive materials for nanotechnology in biochemistry and medicine. In this book, the author review work performed dealing with the DNA structure and functionalities, interactions between DNA, noble metal nanoparticles, surface active agents, solvents and other additives. Particular attention is given to how the DNA's chain length and the DNA conformation affect the interaction and structure of the nanoconjugates and nanostructures that are formed. Also discussed are the recent advances in the preparation, characterization, and applications of noble metal nanoparticles that are conjugated with DNA aptamers and oligomers. The advantages and disadvantages of functionalized nanoparticles through various detection modes are highlighted, including colorimetry, fluorescence, electrochemistry, SPR, and, mass spectrometry for the detection of small molecules and biomolecules.

Book excerpt: Metal nanoparticles that have already found numerous applications in science and technology may be obtained in different ways. In the opening study included in Metal Nanoparticles: Properties, Synthesis and Applications, several factors affecting metal nanoparticle morphology in island films are determined. The formation of islet metal films during their deposition in the process of thermal evaporation on a dielectric substrate and their spontaneous changes at room temperature are also described.Following this, the authors present their experimental results on synthesis, modification and destruction of silver nanoparticles in the bulk and surface of silicate glasses. Special attention is paid to the effects of laser and electron-beam irradiation on the above-mentioned processes.The authors go on to review the synthesis of embedded noble metal nanoparticles and their optical properties and potential applications in surface enhanced Raman scattering. The optical properties of NMNPs due to the localized surface plasmon resonance and the enhanced local electromagnetic field which govern their SERS activity will be discussed along with their fundamental mechanisms.The effects of zinc, titanium, copper and oxide thin films with nanostructured surfaces and iron oxide and silver nanoparticles on Enterococcus hirae and Escherichia coli growth and membrane activity are also presented and discussed. The authors suggest that different types of metal nanoparticles could be applied in medicine due to their antimicrobial activity, effeciency in anti-inflammatory effects and potential in anticancer therapy.Next, the development of platinum-metal nanoparticles and their core-shell structures is discussed.

Download or read book Metallic Nanoparticles written by and published by Elsevier. This book was released on 2008-11-21 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metallic nanoparticles display fascinating properties that are quite different from those of individual atoms, surfaces or bulk rmaterials. They are a focus of interest for fundamental science and, because of their huge potential in nanotechnology, they are the subject of intense research effort in a range of disciplines. Applications, or potential applications, are diverse and interdisciplinary. They include, for example, use in biochemistry, in catalysis and as chemical and biological sensors, as systems for nanoelectronics and nanostructured magnetism (e.g. data storage devices), where the drive for further miniaturization provides tremendous technological challenges and, in medicine, there is interest in their potential as agents for drug delivery.The book describes the structure of metallic nanoparticles, the experimental and theoretical techniques by which this is determined, and the models employed to facilitate understanding. The various methods for the production of nanoparticles are outlined. It surveys the properties of clusters and the methods of characterisation, such as photoionization, optical spectroscopy, chemical reactivity and magnetic behaviour, and discusses element-specific information that can be extracted by synchrotron-based techniques such as EXAFS, XMCD and XMLD. The properties of clusters can vary depending on whether they are free, deposited on a surface or embedded in a matrix of another material; these issues are explored. Clusters on a surface can be formed by the diffusion and aggregation of atoms; ways of modelling these processes are described. Finally we look at nanotechnology and examine the science behind the potential of metallic nanoparticles in chemical synthesis, catalysis, the magnetic separation of biomolecules, the detection of DNA, the controlled release of molecules and their relevance to data storage.The book addresses a wide audience. There was a huge development of the subject beginning in the mid-1980s where researchers began to study the properties of free nanoparticle and models were developed to describe the observations. The newcomer is introduced to the established models and techniques of the field without the need to refer to other sources to make the material accessible. It then takes the reader through to the latest research and provides a comprehensive list of references for those who wish to pursue particular aspects in more detail. It will also be an invaluable handbook for the expert in a particular aspect of nanoscale research who wishes to acquire knowledge of other areas.The authors are specialists in different aspects of the subject with expertise in physics and chemistry, experimental techniques and computational modelling, and in interdisciplinary research. They have collaborated in research. They have also collaborated in writing this book, with the aim from the outset of making it is a coherent whole rather than a series of independent loosely connected articles. * Appeals to a wide audience* Provides an introduction to established models and techniques in the field* Comprehensive list of references
