Abstract

The light-addressable potentiometric sensor (LAPS) belongs to the class of field-effect-based sensor devices. Derived from early investigations on ion-selective field-effect transistors (ISFETs) [1], researchers first developed the electrolyte-insulator-semiconductor (EIS) capacitance to investigate the complex electrochemical- and surface mechanisms of the ISFET-gate region [2-4]. This was a consequential step, and followed the same way as the traditional development of MOSFETs (metal-oxide semiconductor field-effect transistor) and MOS (metal-oxide semiconductor) capacitances [5-8]. Due to the relatively simple manufacturing process and simple encapsulation, at the same time (bio-) chemical sensor development started to use EIS structures as an individual sensor platform [9-12].
