摘要：

Screen-printed biosensor has been prepared by immobilising glucose oxidase on ruthenized-carbon working electrode. The 3-electrodes system was exploited to measure alkaline phosphatase activity in solution by addition of its substrate glucose-6-phosphate. Alkaline phosphatase can be inhibited by organophosphorus- (OP-) based pesticides. Incubation of only 10 minutes allows the determination of 15 ppb of specific compounds.
