Abstract This paper gives a brief survey on biologically sensitive FEDs (field‐effect devices) and introduces some recent approaches in this field. Basic concepts, functional principles and current trends in research and development for namely, ISFETs (ion‐sensitive field‐effect transistors), capacitive EIS (electrolyte‐insulator‐semiconductor) sensors and LAPS (light‐addressable potentiometric sensor) structures will be presented.
