Chain Conformation before Adsorption

Before long-term hemocompatibility can be expected for any material, the nature of polymer surface-protein interaction must be established in more detail the way in which the polymer surface alters itself (rotation of segments, side groups, chain refolding, etc.) in response to the protein species the way the protein is altered in conformation (if at all) upon adsorption by the surface and how this conformational change provokes platelet retention. Of course, longer-term ex vivo or in vivo studies also will be necessary.
