Photoelectric current as a highly sensitive readout for potentiometric sensors
Xu Hun, Xiaoli Xiong, Jiawang Ding, Wei Qin
Abstract
We report here a general strategy to read out potentiometric signals via a photoelectrochemical method. The photocurrent at a working electrode coated with a ZnSe/r-GO composite can be modulated by a polymeric membrane ion-selective electrode that works as a reference electrode.
