Physico-chemical characterizations of PLGem and GemPo. Transmission Electron Microscopy (TEM) images of (A) PLGem and (E) GemPo and their corresponding size distribution (B and F, respectively) and mean size histograms (C and G, respectively) as detected by Dynamic Light Scattering (DLS). Gemcitabine loading onto (D) PLGA and into (H) liposomes are graphed based on UV-visible spectroscopy at λ = 268 nm.
