原始语种摘要: In this work, stable superparamagnetic core-shell Fe₂B@SiO₂ nanoparticles were prepared by "one pot" chemical reduction of ferric ion salts with NaBH₄ and silica shell coating in the presence of citric acid stabilizer. The X-ray (XRD) and selection of electron diffraction (SAED) revealed that Fe₂B@SiO₂ nanoparticles were chiefly composed of silica shell and Fe₂B with a small amount of α -Fe. Then, graphene oxide (GO) was assembled onto core-shell Fe₂B@SiO₂ nanoparticles for Epirubicin (EPI) loading and releasing, and the adsorption isotherm of EPI on Fe₂B@SiO₂@GO was analyzed. The results showed, the adsorption process includes two steps, due to the π - π stacking effect of EPI on the Fe₂B@SiO₂@GO. The EPI loading efficiency of the magnetic nanoparticles was as high as 90%, while the...
