Physical properties of nanoparticles fabricated based on PLGA polymer. (A) The hydrodynamic size distributions of DOX@PLGA, DOX@PLGA/PD, and DOX@PLGA/PD-C. (B) Serum stability of DOX@PLGA, DOX@PLGA/PD, and DOX@PLGA/PD-C. Nanoparticles were dissolved in 10% FCS and incubated at 37 °C for 7 days. (C) UV-Vis absorption spectra of PLGA, PLDA/PD, DOX@PLGA, and DOX@PLGA/PD. (D) The glass transition temperatures (Tg) of PLGA polymer, DOX@PLGA and DOX@PLGA/PD measured by DSC.
