Prior studies demonstrated that the properties of chemically synthesized polyaniline could be modified by the type of synthesis - electrochemical, chemical, or potential cycling methods (1–5). In addition the optical properties of polyaniline could be controlled by the substituents on the nitrogen or aromatic ring (6,7). Enzyme-catalyzed polymer syntheses in organic solvents with different amounts of water were described in earlier publications (7–10), and nonlinear optical properties of some of these polymers were reported (11). This paper describes the horseradish peroxidase-catalyzed synthesis of polyaniline and the evaluation of its optical properties to determine differences, if any, between this polyaniline and those chemically synthesized.
