a Photograph showing the AuNP-integrated silicone-covered SEMS (left) and the conventional silicone-covered SEMS (right). b Light microscope image showing that the AuNPs were integrated into the silicone membrane of the SEMS. c Scanning electron microscope image showing the gold nanospheres with an average diameter of 20 nm. d Bar graph showing the amount of gold ions released from the AuNP-integrated silicone-covered SEMSs into phosphate-buffered saline at 37 °C over a span of 28 days. AuNP, Gold nanoparticle; SEMS, Self-expandable metal stent
