The effect of temperature on the electrochemical properties of copper-DNA membranes.
The influence of temperature, electrode plate metals and protamine on the membrane potential of an electrochemically prepared copper-DNA (Cu-DNA) membrane (size, 2.5 X 6 cm; thickness, 80 micron; Cu/P molar ratio, 0.4) was investigated. The results obtained showed that the membrane potential increased with temperature as well as with increasing order of ionization tendency of the divalent metals used, and decreased with an increase of protamine bound to the membrane. These results indicated that electrons accumulated on the anode side, and positive holes formed on the cathode side, of a Cu-DNA membrane prepared by electrolysis.
