A novel amperometric method for biochemical substrates consuming oxygen in their enzyme reactions is proposed. This method is based on the measurement of the current peak observed when the sample solution is dropped on the thin membrane dipped in the enzyme solution, which is placed on the oxygen ga
## 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
