A Reagentless Aptamer Sensor Based on a Self-Powered DNA Machine for Electrochemical Detection of AFB1
Here, we developed a novel reagentless aptamer sensor for the detection of aflatoxin B1 (AFB1) that uses a DNA walker strategy and bisferrocene to enhance the signal. First, the special binding of AFB1 and AFB1 aptamer activates the DNAzyme strand. Then, with the aid of Mn 2+ , the DNAzyme strand se...
