DOX and RAL release from DPPC liposomes carried out at 37°C and pH 7.4 in 137 mM PBS. 1.88 mM of DOX and 1.98 mM RAL were encapsulated after 20 h of dialysis which corresponds to encapsulation efficiency of 94.5 and 99.3% respectively. Cryo-TEM images of corresponding a DOX and b RAL containing liposomes indicating no difference in the morphology. Scale bar is 200 nm for the TEM images
