The biophysical properties of PEG functionalized PS nanospheres from protein adsorption, blood compatibility, cell compatibility and cell penetrability showed the nanoparticles with high biocompatibility. These results indicated that PEG modified PS nanospheres showed outstanding properties as low size distribution （0.164）, high encapsulation efficiency （98.3%）, long re-calcification time （50% than positive control）, low hemolysis ratio （3.19%） and high cell viability （95.3%）. This work could be used as a good drug delivery system for CsA.展开更多

As2O3-1oaded PLGA nanocapsules （As2O3-PLGANCs） were prepared by double emulsion-solvent evaporation method and were optimized by univariate analysis in combination with orthogonal experimental according to several factors. The optimized As2O3-PLGA NCs presented suitable physical stability, favorable size of （200.2± 10.6） nm （PDI=0.117 ±0.008）, spherical shape, and high encapsulation efficiency （92.48%± 2.14%）. The in vitro suspension stability of the NCs was excellent. The release of As2O3 from the NCs showed pH responsive release characteristics. The NCs can be efficiently taken up by SMMC-7721 cell and showed excellent antitumor efficacy against SMMC-7721 cell line. Then, As2O3-PLGA NCs could be considered as a promising formulation for the pH dependent release of As2O3 in cancer cells and enhance the anti-solid tumor effects of As2O3.展开更多
