Abstract
An electrochemical detector includes a substance selection layer disposed on a semiconductor layer, and the substance selection layer is arranged to interact with a target substance so as to alter an electrical characteristic of the semiconductor layer. A method for fabricating an electrochemical detector is also disclosed.
Claims25
An electrochemical detector comprising:
- a substance selection layer disposed on a semiconductor layer;
- a substrate including an insulating material, the substrate disposed under the semiconductor layer such that the substrate is opposite the substance selection layer with respect to the semiconductor layer;
- and
- only two electrodes, each disposed on or above the substance selection layer thereby forming a two-terminal device;
- wherein the substance selection layer includes a polymer layer functionalized with dioxaborinane and crown ether groups for accommodating at least one molecule of a target substance so as to alter an electrical characteristic of the semiconductor layer, and wherein the insulating material includes at least one of polymer, glass and ceramic.
