Preparation and characterization of doxorubicin-loaded magnetic anticancer nanoparticles

摘要

Doxorubicin(ADM)-loaded magnetic anticancer nanoparticles, using Fe3O4 as core,doxorubicin as model drug and polyvinylpyrrolidone(PVP) as matrix, were prepared by inverse emulsion polymerization. The experimental results showed that the average diameter of Fe3O4 particles was 19.8nm.The X-ray diffraction indicated that the prepared Fe3O4 particle was pure cubic Fe3O4.The results obtained by SEM showed the magnetic nanoparticles under optimal operating condition had a smooth spherical surface, LLS showed an average size of 78.7nm. And IR results demonstrated that they consisted of ADM,PVP and Fe3O4.
