Characterization of C48/80 loaded and unloaded chitosan nanoparticles. (A) Size and zeta potential were measured by dynamic light scattering and electrophoretic light scattering, respectively, with a Delsa™ Nano C. C48/80 loading efficacy was measured by a colorimetric method. Mean ± SD, n ≥ 3. (B) SEM images of (1) Chi NP and (2) Chi-C48/80 NP. Magnification 15,000×, scale 5 µm.
