Label-free nanobiosensing platforms

Abstract:
People involved in designing and developing biosensing applications have high hopes that their field can benefit from nanotechnology. The term biosensing relates to systems that include electronic, photonic, biologic, chemical and mechanical means for producing signals that can be used for the identification, monitoring or control of biological phenomena. The resulting biosensors are devices that employ biological components such as proteins to provide selectivity and/or amplification for the detection of biochemical materials for use in medical diagnostics, environmental analysis or chemical and biological warfare agent detection. Applying nanotechnology to biosensors opens up novel detection possibilities thanks to the nano-physical properties of certain materials. A lot of research worldwide is devoted to developing nanobiosensors. A group in Switzerland, for example, is working on the development of two different kinds of label-free biosensors. One is a nanowire array, the other an optical biosensor based on localized surface plasmon resonance.
