Abstract

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 about 49 aM.
