Bringing together widely scattered information, Nanosensors: Physical, Chemical, and Biological explores sensor development in the nanotechnology age. This easy-to-read book presents a critical appraisal of the new opportunities in the area of sensors provided by nanotechnologies and nanotechnology-enabled advancements. After introducing nanosensor classification and fundamental terms, the book outlines the properties of important nanomaterials and nanotechnologies used in nanosensor fabrication. Subsequent chapters are organized according to nanosensor type: physical (mechanical and acoustical, thermal and radiation, optical, and magnetic); chemical (atomic and molecular energies); and biological. The final chapter summarizes the current state of the field and discusses future trends. A complete and authoritative guide to nanosensors, this book offers up-to-date information on the fabrication, properties, and operating mechanisms of these fast and reliable sensors. It addresses progress in the field, fundamental issues and challenges facing researchers, and prospects for future development.
