Vapor-based synthesis of maleimide-functionalized coating for biointerface engineering.

Chemical vapor deposition polymerization was used to deposit a novel maleimide-functionalized poly-p-xylylene coating on various substrates. The coated substrates are readily able to undergo thiol-maleimide click reaction under mild conditions. Applications using this coating technology are highlighted in low-protein-fouling modification as well as manipulated attachments and growth of bovine arterial endothelial cells.
