제목 | Magnetite Nanoparticles in Hybrid Aerogel and Magnetic induced Nitinol Stent for Hyeprthermia Application |
초록 | Magnetite nanoparticles have received intensive attractions because of their applications as magnetic carriers in drug targeting and hyperthermia in tumor treatment. However, magnetite nanoparticles with 10 nm in diameter easily aggregate themselves to make large secondary particles. To disperse magnetite nanoparticles, this research paper suggests the infiltration of magnetite nanoparticles into hybrid silica aerogels. Methyltriethoxysilicate (MTEOS) based hybrid silica aerogels were synthesized by a supercritical drying method. To incorporate magnetite nanoparticles into the hybrid silica aerogels, we immersed it into magnetite precursor solution. The infiltration of magnetite nanoparticles were identified by XRD, and TEM. Vibrating Sample Magnetometer analysis showed that the composite of the magnetite and hybrid silica aerogel is superparamagnetic. |
