摘要

A three-dimensionally ordered, macroporous,inverse-opal platinum film was synthesized electrochem-ically by the inverted colloidal-crystal template technique.The inverse-opal film that contains platinum nanoparti-cles showed improved electrocatalytic activity toward glucose oxidation with respect to the directly deposited platinum;this improvement is due to the interconnected porous structure and the-greatly enhanced effective surface area.In addition,the inverse-opal Pt-film electrode responds more sensitively to glucose than to common interfering species of ascorbic acid,uric acid,and p-acetamidophenol due to their different electrochemical reaction mechanisms.Results showed that the ordered macroporous materials with enhanced selectivity and sensitivity are promising for fabrication of nonenzy-matic glucose biosensors.
