the fabrication and operation of a microelectronic conductimetric biosensor is described. the device monitors the change in solution conductance occasioned by the catalytic action of enzymes immobilized over a planar conductance cell comprizing serpentined and interdigitated metal conducor tracks. the output of the instrument was liner over a 3 min period and addition of urea to a sample cell overlaid with immobilized urease. the responses to any given urea concentration were reproducible to within approximately $plus or minus$ 1. the device responds to urea present in serum samples.
