【 摘 要 】

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