Fig. 4

This figure shows the morphological traits of EGCG nanoparticles (A, B) with an average diameter of 13.5 nm and two magnification powers, Exosomes (C) with a diameter of 73.66 nm, and EGCG nanoparticles - loaded exosomes (D) with a diameter of 96.54 nm. (E) shows the size distribution of EGCG nanoparticles, exosomes, and EGCG nanoparticles-loaded exosomes by Dynamic Light Scattering, and it indicates different sizes of the nanoparticles.
