The critical goal of nanobiosensors is to detect any biochemical and/or biophysical signal related to a specific disease at the level of a single or few molecules. Nanobiosensors have been successful for in vitro as well as in vivo detection of several biomolecules. It is expected that this technology will revolutionize point-of-care and personalized diagnostics, and will be extremely applicable for early disease detection. This book starts with a brief introduction of the biosensors and then focuses mainly on the emerging nanobiosensor technologies which are geared towards...
