title: Ultrasensitive and selective DNA detection based on nicking endonuclease assisted signal amplification and its application in cancer cell detection.
abstract: By significantly circumventing the typical problem of high background induced by excess hemin itself, an ultrasensitive DNA amplified detection method is developed based on nicking endonuclease (NEase) assisted strand scission cycle, which is further successfully applied in cancer cell detection.
