Polydopamine–polyethylene glycol–albumin antifouling coatings on multiple substrates

Aqueous-based coatings using combinations of polydopamine (PDA) (as bioadhesive) and grafted polyethylene glycol (PEG) (as antifouling agent) have been reported to reduce biofouling on multiple material surfaces. However, the achievable PEG grafting density and antifouling performance are limited, leaving exposed PDA to provide sites for attachment of proteins and cells. In the present work, we investigate the polymerization of dopamine on …
