Biosensor and Biosensor Manufacturing Method

Biosensor with a Nanostructured Gate Electrode

This technology describes a biosensor comprising source/drain electrodes on a substrate, a gate electrode with a nanostructure, and a sensing material fixed to the nanostructure, along with its manufacturing method.

There has been a demand for practical and cost-effective electrochemical sensors that possess high sensitivity and chemical/physical stability.

This technology enhances the sensitivity and practicality of biosensors by introducing nanostructures into the gate region, which increases the surface area and improves channel current flow.
