This book is written as a reference for researchers and engineers working in sensor and nanotechnology fields. Presented are existing and new sensing methods, as well as advances in nano-materials and devices for sensing applications. The book aims to provide an interdisciplinary approach, discussing chemical and physical nature of nano materials/structure, state of- the-art of active and passive electronic and optoelectronic nanomaterials and devices for sensing applications. The scope of the book includes: presentation of terminologies and basics of sensors and transducers, a thorough explanation of quantum theory related to nanostructures, growth, fabrication, and characterization of nano-structures such as nanowires, nanotubes, quantum dots, quantum wires, bio materials, and well-controlled nanostructures for sensing applications, as well as discussions of the synthesis and design of such materials in order to gain the understanding of novel functional properties which can be obtained by impurity doping and surface modification
Nanotechnology provides us with tools to create functional materials, devices, and systems by controlling materials at the atomic and molecular scales, and at the same time make use of novel properties and phenomena. Considering that most chemical and biological sensors, as well as many physical sensors, depend on interactions occurring within the nano scale range, the impact that nanotechnology will have on the sensor world is significant.
Nanotechnology enabled sensors find applications in several novel fields such as sensing single molecules, bio-hazards, toxic chemicals, gas sensors, process control and diagnostics. Application of nanostructured materials for biological applications, biologically assisted nanofabrication, and the development of next-generation of biosensors and biomedical instrumentation for improved sensing is increasingly attracting interests in the scientific community.
