By anodizing of titanium and then electroplating of Platinum on surface anodized titanium, electrodes with high effective surface catalytic were made. Consideration of surface morphology using scanning electron microscope (SEM) shows that, with anodizing, micro porous layer on titanium surface was prepared. The electro catalytic behavior of this type of electrodes in the isopropanol electro oxi...
urease was immobilized on platinum electrode both by chemical binding and electropolymerization.the conductometric urea biosensor thus prepared showed a detection limit of 4.9×10-5 m and linear dynamic range from 4.9×10-5 to 5.8×10-3 m for urea concentration when the enzyme is covalently immobilized on pt electrodes. conductometric transducers respond to the changes in ionic strength thereby le...
An electrical transducer for urea is described. The excellent stability of various types of urease enzyme electrodes developed in the author's laboratory is due to understanding the parameters which affect immobilized enzyme stability. Preliminary experiments have shown that a liquid layer of urease trapped in a double cellophane layer over a cation electrode may produce a useful enzyme electro...
