The morphology, drug loading capacity, release in vitro and biodistribution in vivo of the nanoparticles were studied.

Drug entrapment efficiency of about 90% (w\/w) and loading capacity of 20% (w\/w) could be achieved. In vitro, the nanoparticles showed an initial rapid continuous release followed by a slower sustained release. After intravenous injection into mice, the nanoparticles showed a slower elimination rate and a much higher drug concentration in liver compared with the sodium ferrate solution, and less distribution to the kidneys and other tissues. Immunohistochemistry indicated that the neoglycoprotein-based nano-particles were taken up specifically by hepatic stellate cells.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n
