Abstract

The invention discloses a sensing device. The sensing device comprises a first electrode layer and a second electrode layer, which are separated by a dielectric layer, and through-holes penetrating the first electrode layer, the second electrode layer and the dielectric layer.

Description

technical field [0001] The present disclosure relates generally to electrochemical detection, and more particularly to a sensing device, such as an electrochemical biosensor. Background technique [0002] Electrochemical biosensors are composed of biological sensitive elements and electrochemical sensors. Biological sensitive components range from the earliest enzyme catalyst electrodes to later DNA, antigens, antibodies, microorganisms, animal and plant tissues, etc. The performance of this type of sensor technology is being continuously improved by employing various modern biotechnologies and chemical modification techniques. [0003] Traditional electrochemical biosensors such as Figure 5 As shown, detection electrodes 506-1, 506-2 are generally processed on a silicon base or other substrate 502. Probe molecules can be attached to the electrodes 506-1 and 506-2, as indicated by the symbol "Y" in the figure. When the fluid sample flows through the channel defined by th...
