Synthesis and characterization of void and EF24-containing PEGylated liposomes. Pegylated liposomes synthesized using a lipid hydration method were further characterized using DLS and TEM. a DLS of void and EF24-loaded liposomes revealed a narrow size distribution with an average diameter of less than 150 nm. b Transmission electron microscopy of void (left panel) and EF24-containing liposomes (right panel) demonstrated spherical morphology and an average diameter of around 120 nm, in line with the data obtained by DLS. c The stabilities of void and EF24-loaded liposomes were determined at three different temperatures (4, 20 and 37 °C) using DLS over a period of 40 days
