  • Methods for functionalizing and coating substrates and devices made according to the methods
    Patent number: 5830539
    Abstract: Methods for coating substrates are described. The methods comprise coating at least a portion of a substrate with particular coating materials. The coating materials can be crosslinked and coated onto a substrate. Alternatively, the coating materials may be covalently bonded to the substrates. The coating materials might themselves functionalize the substrate, or provide a biocompatible coating on the substrate. The coating materials might also include electrophilic or nucleophilic groups that allow for the subsequent reaction of the coating materials with additional reagents. The present invention also provides coated workpieces, particularly medical workpieces having a surface for contacting tissue or blood. These workpieces comprise a first layer and a second layer. The first layer comprises a molecular tether covalently bonded to the surface.
