found to be effective against herpes simplex virus type-1 (HSV-1) infections, with viral binding and shielding as the two putative main inhibitory mechanisms.175 Thermally reduced graphene oxide (rGO) sheets functionalized with biocompatible hyperbranched polyglycerol (hPG) and then sulfated have also been generated as graphene-based heparin biomimetics.176−178 Sulfate-rich polymers like heparan sulfate
