Stability under physiological flow conditions. POSS-PCU and CD34-POSS-PCU coated stents were placed in a flow circuit, calibrated to mimic physiological flow conditions, for 28 days. Confocal microscopy using fluorescent QDs on retrieved films showed the presence of anti-CD34 antibodies on the surface even after being exposed to dynamic flow conditions.
