Fig. 6. Diameter size (A) and zeta potentials (B) of nanoparticles after the centrifugation cycles at 10 000 rpm (9391 × g) (
), 15 000 rpm (21 130 × g) (
), and 20 000 rpm (37 565 × g) (
). Diameter size (C) and zeta potentials (D) of PLGA nanoparticles when different cryoprotectant – polymer ratios were used: pre-treatment (
), sucrose (
), glucose (
), and lactose (
). Data represent mean ± SD (n = 3).
