The object of the invention is to increase the detection specificity of biosensors. The present invention provides a biosensor characterized in that it comprises an identifier substance that can bind to a detection target substance and an electrode that takes the charge of said identifier substance, wherein the biosensor detects the change in the charge density of said electrode generated by the binding of said detection target substance with said identifier substance, the surface of said electrode is coated with polycatecholamine, all or a part of said electrode surface coated with polycatecholamine further has a polymer layer formed thereon which has a molecular imprint having a structure complementary to the molecular structure of the detection target substance formed therein, said polymer layer comprises said identifier substance, and said polymer layer is an ultrathin film layer.
A biosensor comprising an identifier substance that can selectively bind to a detection target substance, and an electrode that takes a charge of said identifier substance, wherein the biosensor detects a change in charge density of said electrode generated by the selective binding of said detection target substance with said identifier substance,
An electrode used in a biosensor, characterized in that:
