NON-FOULING, ANTI-MICROBIAL, ANTI-THROMBOGENIC GRAFT-FROM COMPOSITIONS

摘要

A method for preparing and resulting articles of manufacture comprising a substrate having a surface, a bulk beneath the surface, and a grafted polymer layer on the substrate surface, the substrate surface and the grafted polymer layer, in combination, constituting a modified surface having a fibrinogen adsorption of less than about 125 ng/cm2 in a fibrinogen binding assay in which the modified surface is incubated for 60 minutes at 37 C in 70 µg/mL fibrinogen derived from human plasma containing 1.4 µg/mL I-125 radiolabeled fibrinogen.
