| 摘要 |
<p>The invention relates to novel biosensors capable of detecting metal ion concentrations less than about 10 νg/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 the 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.</p> |
