Abstract

original image

A gradient of functional heparin is fabricated onto a surface chemical gradient of plasma-polymerized allyl amine (see figure). While heparin functionality changes across the gradient, increased adsorption of heparin onto the surface is not accompanied with a continued, corresponding rise in heparin function.
