Claim 0:
1. 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 metalloporphyrins 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;
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-C50 heteroalkynyl, 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; and
wherein M is a metal comprising aluminum, calcium, magnesium, manganese, iron, cobalt, nickel, zinc, ruthenium, palladium, silver, platinum, indium, tin, copper, rhodium, chromium, gallium, osmium, iridium, or derivatives thereof and wherein an oxidation state of the metal comprises I, II, III, IV, V, VI, VII, or VIII.
