摘要
We combined a 3D graphene foam network with a ZnO NRs array and further introduced this mixeddimensional heterostructure into a PEC biosensing system.The 3D graphene served as a conductive matrix and provided an extra-large spatial surface area for more effective synthesis of ZnO NRs,while the ZnO NRs array functioned as a photoactive material to generate charge carriers and provided reaction sites at the surface for glutathione(GSH)oxidation.
