The three-way junction DNAzyme based probe for label-free colorimetric detection of DNA.

Biosensors & bioelectronics - 15 Mar 2013

Tang Shurong, Tong Ping, Li Heng, Gu Fang, Zhang Lan

Abstract excerpt

A novel three-way junction DNAzyme based probe has been designed for the colorimetric sensing of target DNA. Specifically, a DNAzyme-linked hairpin DNA is used as a signal probe. In the presence of target DNA, the signal probe, assistant probe and target DNA can hybridize with each other, resulting in the formation of a three-way junction DNA. At the same time, the signal probe is opened and the DNAzyme sequence...
