| 中文摘要 | the electrochemically polymerized azure a film electrode is reported. the resulting film on a platinum electrode surface was analyzed with electron spectroscopy for chemical analysis (esca). the heterogeneous electron transfer processes of hemoglobin at the polymerized azure a film electrode have been investigated using in situ uv-visible spectroelectrochemistry. the formal potential (e-degrees') and electron transfer number (n) of hemoglobin were calculated as e = 0.088 v versus nhe (standard deviation +/- 0.5, n = 4) and n = 1.8 (standard deviation +/- 0.5, n = 4). exhaustive reduction and oxidation electrolysis are achieved in 80 and 380 seconds, respectively, during a potential step between -0.3 and +0.3 v. a formal heterogeneous electron-transfer rate constant (k(sh)) of 3.54(+/- 0.12) x 10(-6) cm/s and a transfer coefficient (alpha) of 0.28(+/- 0.01) were obtained by cyclic voltabsorptometry, which indicated that the poly-azure a film electrode is able to catalyze the direct reduction and oxidation of hemoglobin. |
