Characterization of PTX-S-S-CPT nanoparticles: (A) hydrodynamic diameters (DH) of prodrug nanoparticles at different concentrations; (B) transmission electron microscopy (TEM) images of assembled prodrug nanoparticles (NPs) at the prodrug concentration of 2 mg/mL. Scale bar, 1 μm; inset images with scale bar of 200 nm; (C) hydrodynamic diameters (DH) and (D) zeta-potential and polymer dispersity index (PDI) of as-prepared NPs at different inner/outer (I/O) fluid flow with the prodrug concentration of 2 mg/mL.
