摘要

We report here on simple and universal method for the highly efficient, electrolytic immobilization of tyrosinase (from Agaricus bisporus), for amperometric biosensing purposes. Tyrosinase has been successfully deposited on the surface of thin, ordered films of copolymerized derivative of thiophene (3-methyl-thiophene/3-thiopheneacetic acid/bis(ethylenedioxythiophene)diphenylamine). The tyrosinase retains well its activity well within the fabricated copolymer matrix. Reduction peaks, observed in cyclic voltam-metry at 0.125 to +0.07 V, were attributed to the reduction of enzymatically liberated quinone species. Considering the fact, that immobilization strategy showed high efficiency, obtained results suggest that the method for phenoloxidase immobilization has a great potential for fabrication of bioelectronics' devices.
