Different properties of surface grafted ds-DNA films resulting from the presence of base-pair mismatches provide the basis for an electrochemical method for the identification of species. A simple electrochemical method for identification of species based on differences in surface grafted ds-DNA film properties resulting from the presence of base-pair mismatches.
