CONDUCTOMETRIC BIO-SENSOR ON BASIS OF RECOMBINANT UREASE FOR DETERMINATION OF CONCENTRATION OF UREA IN WATER SOLUTIONS

摘要

A conductometric bio-sensor based on recombinant urease for determination of concentration of urea in water solutions comprises two pairs of gold interdigitated-finger electrodes, to the first group of those working membrane on the basis of recombinant urease selective to urea is applied, to the second pair of electrodes a reference membrane is applied. The bio-sensor is intended for connection to experimental installation for conductometric measurements.
