Abstract

A three dimensional graphene network (3DGN)@WO₃ nanowire (NW) sensor is proposed which can perform colorimetric and electrochemical sensing techniques to detect H₂O₂, ascorbic acid and dopamine. The 3DGN provides three functions: anchoring, separating, conducting, while the WO₃ NWs maximize surface area and catalyse reactions.
