▎ 摘　　要

NOVELTY - Functionalizing graphene sensor surface, comprises: (a) providing a graphene layer including a surface; (b) binding multiple molecular complexes to the surface of the graphene layer, where each molecular complex includes: a linker molecule configured to couple to the sensor surface at a first linker position, and a binding molecule coupled to the linker molecule at a second linker position different from the first linker position; (c) coupling at least one detector molecules to a first subset of the multiple molecular complexes; and (d) coupling at least one passivation agents to a second subset of the molecular complexes, at least some of the molecular complexes of first subset being different from molecular complexes of the second subset. USE - The method is useful for functionalizing graphene sensor surface. ADVANTAGE - The method is economical and reliable. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating the method for functionalizing graphene sensor surface. 610Graphene layer providing step 620Binding step 630Molecular complex coupling step 640Binding molecule coupling step 650Detector molecules coupling step
