This book provides an overview of the techniques and tools of nanostructure fabrication from state-of-the-art lithography to emerging self-assembly approaches. Top-down and bottom-up methodologies along with hybrid approaches are used to illustrate the fabrication of structures including integrated circuits, semiconductor quantum dots, metallic nanoparticles, carbon nanotubes, molecular structures, nanocomposites, arrays and superstructures. Nanofabrication applications in nanoelectronics, biotechnology, nanomechanical devices and nanophotonics will be examined. This brief will present the core concepts of nanofabrication relevant to researchers and industry in this important and rapidly evolving area.

This book covers the fundamentals of sensor technologies as well as the recent research for the development of environmental, chemical and medical sensor technologies. Chapters include current research on microflow cytometry, microfluidic devices, colorimetric sensors, and the development of low-cost optical densitometric sensors and paper based analytical devices for environmental and biomedical applications. Special focus has been given to nanotechnology and nanostructures- their fabrication, uses and utility in different fields of research such as for the design of tools for medical diagnostics, therapeutics, as well as for detection and estimation of pollutant levels in water and air quality monitoring. This book is intended as a resource for researchers working in the field of sensor development across the world.

Intended to update scientists and engineers on the current state of the art in a variety of key techniques used extensively in the fabrication of structures at the nanoscale. The present work covers the essential technologies for creating sub 25 nm features lithographically, depositing layers with nanometer control, and etching patterns and structures at the nanoscale. A distinguishing feature of this book is a focus not on extension of microelectronics fabrication, but rather on techniques applicable for building NEMS, biosensors, nanomaterials, photonic crystals, and other novel devices and structures that will revolutionize society in the coming years.
