Organic semiconductors (OSCs) for electronic chemical sensors

T.J. Dawidczyk, H. Kong and H.E. Katz,     Johns Hopkins University, USA

Abstract

This chapter discusses an assortment of organic semiconductors used as sensors. Both p- and n-channel semiconductors are used to create architectures such as field-effect transistors. Active layers of small molecules, polymers, carbon nanotubes and graphene are included. Depending on the analyte and organic semiconductor used in the active layer, different levels of responses are achieved, allowing for better selectivity. Receptors have been incorporated into the sensors to further enhance the response and selectivity to specific analytes.
