Direct electron transfer reactions of microperoxidase were achieved with the help of semiconductive zinc oxide nanoparticles on a pyrolytic graphite electrode. The enzyme could also exhibit fine electrocatalytic activity towards the reduction of hydrogen peroxide. Thereby, a hydrogen peroxide biosensor was constructed based on the electrocatalysis of microperoxidase. Further studies revealed that after irradiating the microperoxidase/zinc oxide nanoparticles co-modified electrode with UV light for 4 h, the catalytic ability of microperoxidase could be greatly promoted, which could be beneficial to developing more sensitive hydrogen peroxide biosensors. As comparison, it was found that the catalytic activity of the enzyme would be depressed if microperoxidase/agarose co-modified electrode was irradiated. We supposed it was the photovoltaic effect of the zinc oxide nanoparticles that improved the catalytic ability of microperoxidase. (c) 2006 Elsevier B.V. All rights reserved.
