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...http://www.google.es/patents/US5217594?utm_source=gb-gplus-sharePatente US5217594 - Convenient determination of trace lead in whole blood and other fluids
