We have proposed an electrochemical detection method for DNA molecules based on an extended gate field effect transistor (EGFET) sensing chip which consists of one gold plate for molecule recognition and FET part for signal transduction. DNA Probes were immobilized on the gold plate by forming mixed monolayers of thiolated single-stranded oligonucleotide (HS-ssDNA) and alkanethiols, like 6-hydroxy-1-hexanethiol (6-HHT). Electrode reaction corresponding to the reductive desorption of the adsorbed monolayers in strong alkali solution was presented for quantification of surface density of DNA by ...
