摘要: Abstract The behavior of drug release controlled by magnetic fields (MF) for stainless steel coated with magnetic-gelatin (MAG-GE) hydrogel was investigated in this paper. X-ray photoelectron spectroscope (XPS) and vibrating sample magnetometer were used to evaluate the characterizations MAG-GE interaction surface SUS316L. A model (sirolimus) loaded hydrogel. When applying MF hydrogel, sirolimus rate decreased 1 3 , comparing that without field. This suggests a “close” configuration due aggregation nanoparticles which reduced pore size
