Abrégé
(EN)

The invention relates to novel b of detecting metal ion concentrations less than about 10 .mu.g/dl fluid. Biosensors based on the enzyme isocitrate dehydrogenase are particularly suited for detecting trace lead ion concentrations in water and in blood. Bioelectrodes are fabricated from surface deposited colloidal gold adsorbed enzyme that retains high catalytic activity Other aspects of the invention include detection devices for convenient and rapid measurement of metal ions.
