The detection of biological and chemical species is central to many areas of healthcare and the life sciences, ranging from uncovering and diagnosing disease to the discovery and screening of new drug molecules. Hence, the development of new devices that enable direct, sensitive, and rapid analysis of these species could impact humankind in significant ways. Devices based on nanowires are emerging as a powerful and general class of ultrasensitive sensors for the direct detection of biological and chemical species.

Central to detection is the signal transduction associated with selective recognition of a biological or chemical species of interest. Nanostructures, such as nanowires, offer new and sometimes unique opportunities in this rich and interdisciplinary area of science and technology. The diameters of these nanostructures which are comparable to the sizes of biological and chemical species being sensed and their unique electrical, thermal and optical properties, allow them to be exploited for biosensing.

Here, I will present nanowires synthesized via VLS growth mechanism, electroless or dry etching and discuss on their chemical modifications and their potential applications in biochemistry, biology...
