e aim of using it as a platform material for viral helicase inhibition.211 Initial studies were performed with hepatitis C virus (HCV) NS3212 helicase activity and severe acute respiratory syndrome coronavirus (SARS-CoV).211 These studies were enabled by the evidence that single-stranded nucleic acids can adhere to the surface of GO through π–π stacking interactions between the hexagonal graphitic units of GO and the nucleotides. Beyond therapeutics and diagnostics, graphene is also being pursued as an “engineering” material to enhance the barrier properties of
