ABSTRACT:
The invention relates to a blood-compatible surface comprising a polymer surface and a plurality of conjugates made of linkers and active agents immobilized thereon. The polymer surface contains similar or different structural units that carry carbonyl groups. The linkers contain a structural element that is able to form a hydrogen bridge bond. A polyorganosiloxane acting as the active agent is linked to the linkers.
