| 英文摘要 | The direct electron transfer between hemoglobin (hb) and the glassy carbon electrode (gc) can be readily achieved via a high biocompatible composite system based on biopolymer chitosan (cht) and tio2 nanorods (tio2-nrs). tio2-nrs greatly promote the electron transfer between hb and gc, which contribute to the higher redox peaks. uv-vis spectra result indicated the hb entrapped in the composite film well keep its native structure. the immobilized hb remains its bioelectrocatalytical activity to the reduction of h2o2 with a lower detection limit. a novel, sensitive, reproducible and stable electrochemical biosensing platform of h2o2 based on hb-tio2-cht electrode is explored. |
