A sensitive photoelectrochemical assay of miRNA-155 based on a CdSe QDs//NPC-ZnO polyhedra photocurrent-direction switching system and target-triggered strand displacement amplification strategy

Herein, a new photoelectrochemical (PEC) biosensor based on a photocurrent direction switching system and target-triggered strand displacement amplification strategy was developed for the sensitive detection of microRNA (miRNA)-155, and it showed excellent selectivity and a low detection limit of ab...
