Graphene and layered transition metal dichalcogenides (TMDCs) have attracted enormous attention in the area of biomedical applications for diagnostics, therapeutics, safety/security, and environmental monitoring. Whereas pristine graphene has seen applications in biosensors devices, its derivative GO underwent a wealth of investigation for rapid detection, disinfection of pathogens, and enzyme assays, becoming a platform material for a variety of biomedical applications.207−209 A decade ago, studies started to emerge where GO was employed for enzyme activity assays,210 with the aim of using it as a platform material for viral helicase inhibition.211
