UV-Visible spectra of polyaniline solutions in presence of HBT after polymerization with laccase: A) spectra of polyaniline solutions at 4°C and 25°C, with and without mediator at wavelength between 230–650 nm, using a water bath as reactor; B) spectra of polyaniline between 340–690 nm after polymerization using both water bath (a) and ultrasonic bath (b) reactors.
