Description
Nanosensors are fundamental for the development and progress of research in nanotechnology. These devices have been receiving increasing attention because of the need for detecting and measuring, at the molecular level, chemical and physical properties of toxins, pollutants, and analytes in general. In this chapter, general concepts related to nanosensors as well as concepts related to atomic force microscopy (AFM) and atomic force spectroscopy (AFS) regarding the development of nanosensors and nanobiosensors will be introduced. Nanosensors employing AFM tips and (micro)cantilevers will be addressed with emphasis on theoretical concepts, their advantages and disadvantages, and main applications.
