Polycysteinyldopamine (pCDA), a red hair-inspired polydopamine-like polymer with ionic conductor behavior, can produce smooth and highly adhesive thin films and coatings on quartz, glass and other surfaces, and is shown to markedly accelerate the autoxidation of glutathione at physiological pH via an efficient redox exchange process.
