Zero−Length Cross−Linkers Modify Direct Electron Transfer of
Glucose Oxidase on Pre-Anodized Paper/Carbon Electrodes
for Glucose Biosensors
Author(s): Xiu Gao*
Simple covalent immobilization of Glucose Oxidase (GOX) on a carbon electrode surface with zero-length cross-linkers resulted in the development
of a disposable glucose biosensor with Direct Electron Transfer (DET) of GOX. This glucose biosensor displayed a high electron move rate
(ks,3.363 s−1) as well as great proclivity (km, 0.03 mM) for GOX while keeping intrinsic enzymatic exercises. Moreover, the DET-based glucose
discovery was achieved by utilizing both square wave voltammetry and chronoamperometric procedures, and it accomplished a glucose location
range from 5.4 mg/dL to 900 mg/dL, which is more extensive than most monetarily accessible glucometers. Using the negative operating potential,
this low-cost DET glucose biosensor avoided interference from other common electroactive compounds and displayed remarkable selectivity.
