Abstract:

Evodiamine and Fe3O4 nanoparticles were co-encapsulated by dialysis method with methoxy poly(ethylene glycol)/poly(lactide-co-glycolide)(mPEG-PLGA) as carriers. The magnetic drug carriers were characterized through transmission electron microscope(TEM), Fourier transform infrared spectrum(FTIR), UV-Vis spectrum(UV), in vitro release action, Prussian blue staining, in vitro cytotoxicity and magnetic targeting study. The data suggested that Fe3O4 nanoparticles and drug loaded micelles were spherical morphology with narrow size distribution, and had high entrapment capacity with slow release in vitro release profiles. Furthermore, the Fe3O4 nanoparticles and drug loaded micelles were safe and had magnetic targeting properties.

Key words: Magnetic nanoparticle, Poly(ethylene glycol)/poly(lactide-co-glycolide)(mPEG-PLGA), Evodiamine, Sustained-release, Magnetic targeting property
