Claim 4:
5. A medical device comprising:
a graphene layer;
a self-assembled monolayer disposed on an outer surface of the graphene layer through electrostatic interactions between a partial positive charge on hydrogen atoms of one or more hydrocarbons of the self-assembled monolayer and a π-electron system of graphene; and
wherein the self-assembled monolayer comprises one or more substituted porphyrins or substituted porphyrins of the formula:, wherein each X is independently a heteroatom comprising N, O, P, S, Se, or Si, or absent, such that R is covalently attached to the phenyl group; and
wherein each R functional group independently comprises: —H; any linear or branched C1-C50 alkyl, C1-C50 alkenyl, C1-C50 alkynyl, C1-C50 heteroalkyl, C1-C50 heteroalkenyl, C1-C50heteroalkynyl, or any combination thereof; —RZR, —ZRZR, or —RZRZR , wherein R comprises any identical or different, linear or branched, C1-C50 alkyl, C1-C50 alkenyl, C1-C50 alkynyl, or any combination thereof, and Z can be one or more heteroatom selected from N, O, P, S, Se, or Si; an aryl, heteroaryl, substituted aryl, or substituted heteroaryl; a biphenyl or substituted biphenyl; an aryloxy, arylthio, arylamine, or any substitutions thereof; or any combination thereof.
