Popis: Here we report the first PCB-implemented electrochemical glucose biosensor usingcovalently immobilized glucose oxidase (GOx) on the commercially fabricated PCB electrodesurface, taking particular care on the electrode surface characteristics and their effect on sensorperformance. Based on the results, this assay exhibits a highly linear response from 500 μM to 20mM (R = 0.9961) and a lower limit of detection of 500 μM.
