Characterization of the TAS-loaded polymeric nanoparticles. The morphology of PLGA-TAS (a) and MM-PLGA-TAS (b) nanoparticles was characterized by transmission electron microscopy, and their size distribution was measured via DLS. Zeta potentials of PLGA-TAS (c) and MM-PLGA-TAS (d) nanoparticles. e Drug release kinetics from PLGA-TAS and MM-PLGA-TAS after different durations of dialysis. f Variations of average size and zeta potential of MM-PLGA-TAS in pH 7.4 PBS over 7 days. g Determination of MM-PLGA-TAS/DIR emission spectra by microplate marker. Data are shown as mean ± SD (n = 3). TAS, tasquinimod; PLGA, poly-lactic acid-glycolic acid; MM, macrophage membrane; DIR, infrared dye; DLS, dynamic light scattering.
