| 摘要 |
The present invention provides an anti-thrombogenic and cellular-adhesion coating composition for blood-contacting surfaces. The coating comprises a covalent complex of from 1 to 30 hydrophobic silyl moieties of Formula I:wherein R1 is an C1-18 alkyl or C6-32 aryl group, each R2 is independently selected from the group consisting of C1-18 alkyl and C6-32 aryl, R3 is N or O, n is a number from 1 to 10, directly bound to a heparin molecule via covalent bonding, with an adhesive molecule directly bound to the heparin molecule. In one embodiment, the coating comprises benzyl-(1,2 dimethyl)disilyl heparin, wherein an adhesive molecule, such as fibronectin, is bound to the heparin. |
