Dependent signal quenching and enhancing triggered by bipedal DNA walker for ultrasensitive photoelectrochemical biosensor

Herein, by utilizing bipedal DNA walker as booster to adjust the distance of quencher ferrocene (Fc) and sensitizer methylene blue (MB) to photoactive material perylene-3,4,9,10-tetracarboxylic acid (PTCA), a novel “on-off-super on” photoelectrochemical (PEC) biosensor was proposed for ultrasensitiv...
