The in vivo behaviors of doxorubicin(DOX)-loaded dextran-poly(3-acrylamidophenylboronic acid)(DextranPAPBA) nanoparticles(NPs) were studied.The DOX-loaded NPs had a narrowly distributed diameter of ca.74 nm and mainly accumulated in liver of tumor-bearing mice after intravenous injection as demonstrated by in vivo real-time near infrared fluorescent imaging.The DOX contents in various tissues were quantified and consisted well with the results of fluorescent imaging.The biodistribution pattern of DOX-loaded NPs encourages us to investigate their liver tumor treatment by using an orthotopically implanted liver tumor model,revealing that the DOX-loaded NPs formulation had better antitumor effect than free DOX.
