Abstract

Light-addressable potentiometric sensing units are provided. A light-addressable potentiometric sensing unit comprises a conductive substrate, a metal oxide semiconductor layer, and a sensing layer. The metal oxide semiconductor layer is made of indium gallium zinc oxide, indium gallium oxide, indium zinc oxide, indium oxide co-doped with tin and zinc, tin oxide, or zinc oxide. The wide-band gap characteristic of the metal oxide semiconductor layer enables the light-addressable potentiometric sensing unit to resist the interference from visible light. The light-addressable potentiometric sensing unit therefore exhibits a more stable performance.
