| 中文摘要 | a novel method to fabricate a hydrogen peroxide sensor was developed by immobilizing horseradish peroxidase (hrp) on colloidal an modified ito conductive glass support. the cleaned glass support was modified with (3-aminopropyl)trimethoxysilane (aptms) first to yield an interface for the assembly of colloidal an. then 15 nm colloidal au particles were chemisorbed onto the amine groups of the aptms. finally, hrp was adsorbed onto the surface of the colloidal an. the immobilized hrp displayed excellent electrocatalytical response to the reduction of hydrogen peroxide. the performance and factors influencing the resulted biosensor were studied in detail. the resulted biosensor exhibited fast amperometric response (within 5 s) to h2o2. the detection limit of the biosensor was 8.0 mumol l(-1), and linear range was from 20.0 mumol l(-1) to 8.0 mmol l(-1). furthermore, the resulted biosensor exhibited high sensitivity, good reproducibility, and long-term stability. |
