Morphology and particle size analysis of the OS liposomes. Transmission Electron Microscopy (TEM) photograph of OS liposomes (A) and their lipid bilayer (B), particle size distribution (C), and zeta potential distribution (D). This figure confirms the presence of round liposomes with narrow size distribution (<200 nm) and a negative surface charge.
