摘要

Photoelectrochemical (PEC) sensors have become a recent hot topic in analytical chemistry.Since PEC can well separate the excitation signal (light) from the detection signal (current),it shows many advantages including low background and low applied potential.Consequently,PEC often leads to higher sensitivity than conventional electrochemical and optical methods.
