Effects of surface modification of As2O3-loaded PLGA nanoparticles on its anti-liver cancer ability: An in vitro and in vivo study.

As2O3-loaded nanoparticles (NPs) based on poly (lactic-co-glycolic acid) (PLGA) were prepared by double emulsion-solvent evaporation method. Then Lactose acid (LA) and/or PEG were modified onto the NPs by chemical covalent coupling through -NH2 and -COOH. The FTIR results showed that LA and PEG could be successfully modified onto the surface of the NPs. All… CONTINUE READING
