Micellar peroxidase-catalyzed synthesis of chiral polyaniline (PANI) in the presence of dodecylbenzenesulfonic acid (DBSA) was developed. The effect of DBSA concentration on the catalytic efficiency of horseradish and palm tree peroxidases was examined. Favorable conditions for the enzymatic synthesis of chiral PANI, determined by a multiple factors design, demonstrated that the PANIs with the highest chirality were produced in the presence of low concentrations of optically active camphorsulphonic acid (CSA). Unexpectedly, the chiral PANI was also synthesized in the absence of CSA in feed. The favorable conditions for the enzymatic production of chiral and conducting PANIs were shown to be different. The morphology of the chiral PANI particles was examined by transmission and scanning electron microscopies.
