“…[19][20][21] However, laccase, an environmentally-benign catalyst, which requires milder reaction conditions, has been used in this work for the oxidative polymerization of dopa in aqueous solutions and the mechanism is shown in Scheme 1b. 22 In our present work, the biological coloration of silk fabric by in situ oxidation of dopa using laccase was studied, which combined the bio-inspired dyeing and enzymatic dyeing techniques of textiles. The effects of incubation time and laccase dosage on the polymerization of dopa, catalyzed by laccase, were studied in terms of the K/S values of silk fabrics.…”
