Ultra-sensitive non-enzymatic amperometric glucose sensors based on silver nanowire/graphene hybrid three-dimensional nanostructures

Ultra-sensitive amperometric glucose sensors were developed by the synergistic combination of one-dimensional silver nanowires (Ag-NWs) and two-dimensional graphene sheets in the form of highly porous three-dimensional nano-structures (3D NSs). To achieve this, a simple hydrothermal sol-gel techniqu...
