Preparation and Characterization of Hyaluronic Acid-Polycaprolactone Copolymer Micelles for the Drug Delivery of Radioactive Iodine-131 Labeled Lipiodol

Figure 6

The cytotoxicity of the micelles encapsulated with 131I-lipiodol. After 4 days of incubation, the LDH concentrations of HepG2 cells were increased significantly. It may be due to the increased cell uptake activity and higher stability of 131I-lipiodol loaded HA-g-PCL micelles which contributed to having better 131I-lipiodol control release rates (, ).
