Physicochemical characteristics of ATX-NPs. (A) The average particle size, entrapment efficiency, and zeta-potential of ATX-NPs. (B,C) Representative TEM pictures of ATX-NPs. (D,E) Dynamic laser scattering (DLS) measurement of hydrodynamic size distribution of ATX-NPs. (F) Fluorescence emission spectra of ATX-NPs. (G) Particle size of ATX-NPs during 7 days storage at 4°C. The values represent the mean ± SEM.
