DNA Electrochemical Behaviors, Recognition and Sensing by Combining with PCR Technique

The electrochemical studies on the behaviors and recognition of DNA have attracted cosiderable attention. DNA biosensors based on a nucleic acid hybridization process are rapidly being developed towards the goal of rapid and inexpensive diagnosis of genetic andinfectious deseases. This brief review focuses on the current state of the DNA electrochemical sensors with emphasis on recent advances, challanges and trends. The works on DNA electrochemical behaviors, recognition and detection in our group in the last three years are also introduced.
