Electrical behaviour and evolutionary computation in thin films of bovine brain microtubules

Abstract We report on the electrical behaviour of thin films of bovine brain microtubules (MTs). For samples in both their dried and hydrated states, the measured currents reveal a power law dependence on the applied DC voltage. We attribute this to the injection of space-charge from the metallic el...
