▎ 摘　　要

A novel green one-pot approach for surface modification of graphene oxide into organosulfur modified graphene nanosheets (OS-GNS) is being reported. Alliin (garlic phytochemical) mediated organothiol linkages over OS-GNS facilitated one-step attachment of pre-synthesized gold nanoparticles. In absence of alliin treatment, no Au NP attachment was observed.
