Mapping Tumor Heterogeneity With Quantum Dots

A research team from Emory University has developed a method for mapping the molecular heterogeneity of human prostate tumor biopsies obtained from cancer patients using a mixture of four quantum dots linked to antibodies that can detect cancer-associated proteins. Shuming Nie, the principal investigator of the Emory University and Georgia Institute of Technology Center of Cancer Nanotechnology Excellence, led the research, which was published in the journal ACS Nano.

Nanotechnology As a National Security Issue

Product DescriptionThe projected economic and societal benefits of nanotechnology have propelled global investments by nations and companies. The United States launched the first national nanotechnology initiative in 2000. Since then, more than 60 nations have launched similar initiatives. In 2006, global public investment in nanotechnology was estimated to be $6.4 billion, with an additional $6.0 billion provided by the private sector. More than 600 nanotechnology products are now in the market, generally offering incremental improvements over existing products. However, proponents maintain that nanotechnology research and development currently underway could offer revolutionary applications with significant implications for the U.S. economy, national and homeland security, and societal well-being. These investments, coupled with nanotechnology’s potential implications, have raised interest and concerns about the U.S. competitive position. The data used to assess competitiveness in mature technologies and industries, such as revenues and market share, are not available for assessing nanotechnology. In fact, the U.S. government does not currently collect such data for nanotechnology, nor is comparable international data available. Without this information, an authoritative assessment of the U.S. competitive position is not possible. Alternatively, indicators of U.S. scientific and technological strength (e.g., public and private research investments, nanotechnology papers published in scientific journals, patents) may provide insight into the current U.S. position and serve as bellwethers of future competitiveness. By these criteria, the United States appears to be the overall global leader in nanotechnology. However, other nations are investing heavily and may lead in specific areas of nanotechnology. Some believe the U.S. leadership position in nanotechnology may not be as large as it has been in previous emerging technologies. Efforts to develop and commercialize nanotechnology face a variety of challenges – e.g., technical hurdles; availability of capital; environmental, health, and safety concerns; and immature manufacturing technology and infrastructure. Some advocate a more active federal government role in overcoming these challenges, including funding to aid in the translation of research to commercial products; general and targeted tax provisions; incentives for capital formation; increased support for development of manufacturing and testing infrastructure, standards and nomenclature development, and education and training; creation of science, technology, and innovation parks; and efforts to establish a stable and predictable regulatory environment that keeps pace with innovation. Some support a more limited federal role. Some who hold this view maintain that the market, free from government interventions, is most efficient. They assert that federal efforts can create market distortions and result in the federal government picking ‘winners and losers’ among technologies, companies, and industries. Others oppose federal support for industrial research and applications, labeling such efforts ‘corporate welfare’. Still others argue for a moratorium on nanotechnology R&D until environmental, health, and safety concerns are addressed.

Nanotechnology Applications to Telecommunications and Networking

Product DescriptionBe a part of the nanotechnology revolution in telecommunications This book provides a unique and thought-provoking perspective on how nanotechnology is poised to revolutionize the telecommunications, computing, and networking industries. The author discusses emerging technologies as well as technologies under development that will lay the foundation for such innovations as: * Nanomaterials with novel optical, electrical, and magnetic properties * Faster and smaller non-silicon-based chipsets, memory, and processors * New-science computers based on Quantum Computing * Advanced microscopy and manufacturing systems * Faster and smaller telecom switches, including optical switches * Higher-speed transmission phenomena based on plasmonics and other quantum-level phenomena * Nanoscale MEMS: micro-electro-mechanical systems The author of this cutting-edge publication has played a role in the development of actual nanotechnology-based communication systems. In this book, he examines a broad range of the science of nanotechnology and how this field will affect every facet of the telecommunications and computing industries, in both the near and far term, including: * Basic concepts of nanotechnology and its applications * Essential physics and chemistry underlying nanotechnology science * Nanotubes, nanomaterials, and nanomaterial processing * Promising applications in nanophotonics, including nanocrystals and nanocrystal fibers * Nanoelectronics, including metal nanoclusters, semiconducting nanoclusters, nanocrystals, nanowires, and quantum dots This book is written for telecommunications professionals, researchers, and students who need to discover and exploit emerging revenue-generating opportunities to develop the next generation of nanoscale telecommunications and network systems. Non-scientists will find the treatment completely accessible. A detailed glossary clarifies unfamiliar terms and concepts. Appendices are provided for readers who want to delve further into the hard-core science, including nanoinstrumentation and quantum computing. Nanotechnology is the next industrial revolution, and the telecommunications industry will be radically transformed by it in a few years. This is the publication that readers need to understand how that transformation will happen, the science behind it, and how they can be a part of it.

Nanotechnology Applications in Coatings

Product DescriptionNanotechnology based coating products have shown remarkable growth in recent years. This book begins with an overview chapter on recent scientific and technological advancements in nanotechnology applications in this field. Subsequent chapters cover, in detail, a number of key applications of nanotechnology in coatings, along with the related fundamental science. Some contributions focus on issues related to inorganic/organic nanocomposite coating films, including dispersion of inorganic nanoparticles and nanoclays. Surface Functionalized nanoparticles, predispersed inorganic nanoparticles that can be mixed with existing organic coating formulations and organic/inorganic hybrid latexes are approaches discussed for preparation of nanocomposite coatings having improved scratch, corrosion, and UV resistance. Several chapters address nanostructure development approaches to impart specialized functionality and performance to coatings. Nanoporous adhesive microbial ink-jet ink for miniature biosensors and biocatalysts and nanostructured conjugated polymer networks are discussed. Characterization of nanostructure and nanoparticle dispersion in coatings is a difficult challenge, and this challenge is addressed in several chapters. Assessment of phopocatalytic activity of nanoparticles, use of atomic force microscopy, applications of Nano-Indentation for mechanical property measurements, and nano-thermal analysis are discussed. Size determination techniques suitable for nanoparticles are also reviewed. The highly multidisciplinary nature of the field is evident throughout the book.
