Bio-chem-FETs: field effect transistors for biological sensing

N. Chaniotakis and M. Fouskaki,    University of Crete, Greece


Field effect transistors (FETs) are electrochemical transducers upon which micro-sized solid-state chemical sensors and biosensors, the so-called Bio-chem-FETs, can be developed. The chapter first discusses the key issues of FET operation. It then describes the ways of introducing chemical and biochemical sensitivity and selectivity to analytes, using either chemically activ sensing elements or biological recognition elements. The new advances in Bio-chem-FET design, based on novel carbon and inorganic nanomaterials, are then presented. Finally, the current analytical limitations are presented, followed by ...
