| Abstract: | CdS nanoparticles cast on the glassy carbon (GC) electrode was used to immobilize hemoglobin (Hb). The CdS nanoparticles could provide a favorable microenvironment for direct electron transfer between the electrode and the immobilized proteins. In addition, the immobilized Hb showed stable bioelectrocatalytic activity for the reduction of H2O2. |
