ABSTRACT
<p><b>AIM</b>To study a new way to prepare high-dosage paclitaxel entrapped magnetic targeted nanoparticles and evaluate its quality.</p><p><b>METHODS</b>Fe3O4 nanoparticles are prepared by co-depositing, at the same time ultrasonic is used to decrease soft agglomerate of nanoparticles and increase disperse level of it. The property of nanoparticles surface is improved to make the integrating of liposome and nanoparticle to be tighter. At last, paclitaxel entrapped magnetic solid liposome nanoparticles have been prepared by microemulsion-curing under low-temperature. The loading efficiency and encapsulating rate were determined by reverse-phase high-perfomance chromatography.</p><p><b>RESULTS</b>The nanoparticles have spherical shape. Diameter of nanoparticle ranged from 150 nm to 170 nm. 98.29% of the drug is entrapped in the particle.</p><p><b>CONCLUSION</b>Magnetic susceptibility of nanoparticles is high, and the nanoparticles meet with the demand of targeted delivery system.</p>
