Improved Stability of Continuous Operation of Lactate Oxidase-hydrogel Electrodes Using Os(bipyridine)2Cl-pendant Poly(vinyl Imidazole) [PDF]

Keywords: lactate oxidase, lactate sensor, redox hydrogel, stability, cross-linker

Hydrogel-modified redox electrodes are fabricated using lactate oxidase and a poly(vinyl imidazole) polymer containing an Os(bipyridine)2Cl complex to facilitate the improved continuous measurement of lactate concentration. The stability of a MgO-templated carbon modified with a hydrogel was improved by quaternizing 10 mol% of the imidazole content of poly(vinyl imidazole) with bromoethylamine. Stability was further improved by cross-linking the polymer using ethylene glycol diglycidyl ether and sorbitol polyglycidyl ether, which increased the density of the hydrogel structure.
