摘要: Nanoporous gold (NPG) thin films were found to be capable of directly and reliably sensing phenol and catechol using amperometric technique at neutral conditions without enzyme. The sensing of phenol and catechol was conducted on NPG based on their different electro-oxidation potentials. The NPG thin films exhibited not only good sensitivities but also large linear detection ranges in comparison with the current state of the art enzyme-based electrodes. They also had a good resistance against surface fouling, enabling detection at …
