Abstract

The present disclosure relates to a biosensor. The biosensor according to an embodiment of the present disclosure comprises a substrate; a source electrode and a drain electrode on the substrate; a graphene layer on the substrate, and connected to the source electrode and the drain electrode; a first doping layer on an area including one end of the graphene layer; a second doping layer on an area including the other end of the graphene layer and separated from the first doping layer; and a first and a second passivation layer on the first and the second doping layer, respectively. Accordingly, the sensing sensitivity of a graphene-based sensor may be improved.
