英文摘要: This study reported the development of a p-n heterojunction photoelectrochemical biosensor using a G-quadruplex as the recognition system. The n-type ZnO nanorods and p-type BiOI nanoflakes were combined to form the heterostructure by in situ growth of BiOI attributed to a simple impregnating-hydroxylation method. This simple p-n heterojunction fabrication method could facilitate the development of rapid and sensitive visible light activated PEC sensors. In this study, the ZnO/BiOI photoelectrode showed a rapid photocurrent decrease in the presence of Pb2+ due to the electron withdrawing effect of hemin which bound with the G-quadruplex/Pb2+ complex. This PEC biosensor exhibited a good response following the concentration of Pb2+ in the range from 10 to 100 mu M.
