Abstract
DC conductivity measurements have been carried out on an enzyme amylase (EC 3.2.2.1) in solid pellet form, provided with silver-coated electrodes. The results are presented in the form of current–voltage characteristics for the temperature range 300–360K. The analysis of the results obtained by plotting the temperature dependence of current density, Poole–Frenkel plots, Schottky plots, Richardson plots and Arrhenius plots shows that the Schottky–Richardson mechanism is responsible for the observed d.c. conduction in amylase. Furthermore, the presence of Schottky barriers at the metal electrode–insulator interface suggests that, by using silver electrodes, satisfactory contacts can be achieved for electrical investigations on biomaterials. © 1998 Society of Chemical Industry
