Cooperative Amplification-Based Electrochemical Sensor for the Zeptomole Detection of Nucleic Acids

In this work, we developed a multiple-amplification-based electrochemical sensor for ultrasensitive detection of nucleic acids using a disease-related sequence of the p53 gene as the model target. A capture probe (CP) with a hairpin structure is immobilized on the electrode surface via thiol–gold bo...
