Abstract:
Based on the "Y" junction structure and restriction endonuclease-aided target recycling strategy, an electrochemical biosensor for DNA detection was developed. This universal biosensor was suitable for detecting different sequences of target DNA by changing the sequence of capture and assistant strands.
