Abstract: A biomarker detection sensor includes a substrate; a working electrode formed by laser-scribing directly into the substrate so that a material of the substrate is transformed into graphene; a metal nanostructure formed on a graphene surface of the working electrode, wherein the metal nanostructure is shaped as a tree with plural branches extending away from the graphene surface; an aptamer covering a first surface area of the metal nanostructure; a reference electrode; and a counter electrode.
