Abstract
In one aspect, a sensor for detecting a drug of abuse (DOA) in a sample is disclosed. In some embodiments, the sensor includes a graphene layer, a plurality of binding agents, which bind to the DOA, coupled to said graphene layer to generate a functionalized graphene layer, and a plurality of electrical conductors electrically coupled to said functionalized graphene layer for measuring an electrical property of said functionalized graphene layer. While in some embodiments, such binding agents are monoclonal antibodies, in other embodiments they are polyclonal antibodies.
