An amperometric glucose biosensor was developed using an anionic clay matrix of hydrotalcitic nature (Ni/Al–NO 3 HT) as enzyme support, which was electrochemically synthesized at −0.90V versus SCE, using a rotating disk Pt electrode to assure homogeneity of the electrodeposition suspension. The biorecognition element was glucose oxidase (GOx) immobilized on HT during the electrosynthesis,...
Pt electrodes, modified with a directly electrosynthesised film of Ni/Al-NO 3 hydrotalcite were evaluated as amperometric sensors for oxidizable substrates in flow systems. The optimization of the operative parameters has been carried out using EtOH as test analyte, NaOH as carrier electrolyte and applying a constant potential. Analytical results in terms of linear range, limit of detection...
