## Abstract The preparation of gas diffusion electrodes and their use in an amperometric enzyme biosensor for the direct detection of a gaseous analyte is described. The gas diffusion electrodes are prepared by covering a PTFE membrane (thickness 250β ΞΌm, pore size 2β ΞΌm, porosity 35%) with gold, pla

A sensitive modified carbon paste electrode for the direct determination of cholesterol is described. Both cyclic voltammetric and chronoamperometric techniques are used. The electrode was modified with hydroxymethyl ferrocene and horseradish peroxidase. Cholesterol oxidase and cholesterol ester hyd
An amperometric enzyme electrode for the determination of aspartame in protein-free samples has been constructed. It is based on the coimmobilization of an aspartamehydrolyzing enzyme, aspartate aminotransferase, and glutamate oxidase on an Immobilon membrane. The electrode response is linear from \
## An amperometric method utilizing an enzyme electrode was developed for the determination of the glucose content of instant coffee. The electrode was constructed by combining an oxygen electrode with a p-o-glucose ozidase-immobilized collagen membrane. Samples of instant coffee were analysed and
