Coating characterization and stability over time. Evaluation of the WCA measured before and after the coating deposition, and at different time points (1 week, 2 weeks, 3 weeks, 4 weeks, and 8 weeks) following storage under physiological conditions (samples immersed in PBS at 37 °C, 200 rpm oscillation). SBMA-based coating fabricated with (a) Strategy 1, (b) Strategy 2, (c) Strategy 3 and MPC-based coating fabricated with (d) Strategy 1, (e) Strategy 2, (f) Strategy 3. * = p < 0.05, ** = p < 0.01, *** = p < 0.001, **** = p < 0.0001. PEEK = polyether-ether-ketone, SBMA = [2-(methacryloyloxy)ethyl]dimethyl-(3-sulfopropyl)ammonium hydroxide, MPC = 2-methacryloyloxyethyl phosphorylcholine, PDA = polydopamine.
