Biosensor and its Manufacturing Method

Biosensor with Increased Sensing Material Binding Area

This technology describes a biosensor that selectively reacts to target substances by arranging sensing material in both the channel region and the gate electrode region, along with its manufacturing method.

Conventional biosensors had limitations in improving sensitivity due to the restricted binding area of the sensing material.

This technology improves the sensitivity of biosensors by increasing the binding area through the arrangement of sensing material in both the channel region and the gate electrode region.
