摘要：

A peroxidase modified membrane was stabilized by thin plasma polymer layer deposited using the monomers allylalcohol or hexamethyldisilazane. In comparison to the uncoated enzyme membrane, there is a significant operational stability improvement of the hydrogen peroxide detection. H2O2 can be detected in the range between 4 and 1000 muM. The sensor is stable for more than 1000 detections under flow injection conditions. (C) 2001 Elsevier Science B.V. All rights reserved.
