Enzymatic Synthesis of Sulfonic Acid Derivatives

Recently, the use of enzymes as biological catalysts in the synthesis of polyanilines has attracted great interest due to their environmental 

445 nm appeared at higher pH (above pH 9) reportedly due to dedoping of the polymer. This polymer was shown to be soluble in water at all pH values, which makes it suitable material for self-assembly into organized structures with biological macromolecules such as enzymes for fabrication of biosensors. The conductivity of polymer, however, was very low (10 S/cm) and the average molecular weight was only approximately 18 000 g/mol. Poly(p-aminobenzoic acid) was also soluble in neutral and alkaline conditions and exhibited a conductivity around 10 S/cm.
