An ultrasensitive electrochemiluminescence biosensor for multiple detection of microRNAs based on a novel dual circuit catalyzed hairpin assembly†
Abstract
A novel double-hairpin DNA inducing a dual circuit catalyzed hairpin assembly (DC-CHA) strategy was proposed to fabricate electrochemiluminescence (ECL) biosensors for multiple target (microRNA-21 and microRNA-155) ultrasensitive detection.
