An Enzymatic Biosensor with Amperometric Detection in a Flow Injection Analysis for the Determination of L-lactic Acid: Development and Application

Original language description

An amperometric biosensor consisting of an enzymatic mini-reactor (lactate oxidase covalentlynattached to −NH2 functionalized mesoporous silica powder SBA−15 using glutaraldehyde) andna silver amalgam-based screen-printed electrode acting as a transducer was developed for thendetermination of L-lactic acid (LA) in FIA. The detection potential of −0.9 V vs. Ag pseudoreferencenelectrode was applied for cathodic detection of enzymatically consumed oxygen.nUnder the optimized conditions, the constructed biosensor enabled selective determination ofnLA with a micromolar limit of detection. Importantly, the proposed biosensor representednexcellent operational stability after ≥350 measurements. Finally, it was successfully applied tonreal sample analysis.
