Ultrasensitive DNA electrochemical biosensor based on MnTBAP biomimetic catalyzed AGET ATRP signal amplification reaction.

In this paper, an ultrasensitive, highly selective and green electrochemical biosensor for quantifying DNA sequences (aM DNA) based on a MnTBAP catalyst for AGET ATRP reaction is proposed. For the first time, a combination of biomimetic catalyzed free radical polymerization and DNA electrochemical biosensing was used as a signal amplification strategy.
