3D nanoporous Ag@BSA composite microspheres as hydrogen peroxide sensors.
3D nanoporous Ag@BSA composite microspheres were successfully prepared through a protein-directed approach. Electrochemical measurements show that the nanoporous Ag@BSA composite microspheres exhibit excellent electrocatalytic activity towards the reduction of H2O2. A linear range of 5 μM-1.5 mM and a lower detection limit of 0.16 μM were recorded. The sensing performance might be attributed to the 3D micro/nano architecture and nanoporous characters.
