Magnetic nanoparticle loaded biodegradable vascular stents for magnetic resonance imaging and long-term visualization

Abstract

Fe 3 O 4 superparamagnetic iron oxide nanoparticles (SPIONs) were synthesized to modify the BDS by ultrasonic spraying. The fabricated SPION-BDS can be entirely visualized under MR imaging, and the stent degradation can also be long-term monitored.
