We report a simple and facile protocol to fabricate mussel-inspired polydopamine (PDA) gradients on different surfaces. An oxygen diffusion phenomenon was used for dopamine autoxidation form thickness of PDA substrates. These showed gradual changes in thickness, roughness, wettability light transmittance.
