Using Self-Polymerized Dopamine to Modify the Antifouling Property of Oligo(ethylene glycol) Self-Assembled Monolayers and Its Application in Cell Patterning

We report a one-step, mild method to modify antifouling oligo(ethylene glycol)-terminated self-assembled monolayers. We demonstrate for the first time that self-polymerized dopamine, previously reported as an underwater adhesive, can be patterned on typical antifouling surfaces by microfluidic patterning or microcontact printing. The patterns can be applied in spatiotemporal cell patterning.
