Abstract
In this paper, a chip is designed to carry out combined pH and impedance sensing of DNA to create diagnostic devices with improved performance. Circuit simulations in Cadence indicate the ability of the chip to detect pH and impedance changes. Electrochemical pixels also incorporate DNA trapping using dielectrophoresis, to concentrate DNA at sensing regions and increase the observed signal. FEM simulations show that the electrodes are able to trap DNA under DEP.
