A novel dual mode capacitor biosensor for real-time, label-free DNA detection

A novel biosensor working in both MOS capacitor and electric double-layer capacitor mode for real-time, label-free DNA detection is presented. The former mode measures density and polarity of charged biomolecules to be monitored, while the latter mode appears to reveal more of surface-molecule interactions and offers high sensitivity and easiness for diagnosis. A combined mode-utilization yields optimal complementary information of significance
