| 中文摘要 | a reagentless amperometric hydrogen peroxide biosensor was developed. horseradish peroxidase (hrp) was immobilized in a novel sol-gel organic-inorganic hybrid matrix that is composed of silica sol and a grafting copolymer of poly(vinyl alcohol) with 4-vinylpyridine (pva-g-pvp). tetrathiafulvalene (ttf) was employed as a mediator and could lower the operating potential to -50 mv (versus ag/agcl). the sensor achieved 95% of the steady-state current in 15 s. linear calibration for hydrogen peroxide was up to 1.3 mm with the detection limit of 2.5 x 10(-7)m. the enzyme electrode retained about 94% of its initial activity after 30 days of storage in a dry state at 4 degreesc. |
