Traditional electrochemical DNA biosensors need DNA immobilization on the electrode surface,which is tedious and time consuming.In this study,a simple but sensitive electrochemical DNA biosensor had been designed to determine target DNA species related to oral cancer in saliva,which combines the immobilization-free electrochemical method with the signal amplification of nicking endonuclease assisted target recycling.
