Effects of the disaccharide concentration and the extrusion speed on the size of unilamella vesicles

► The effect of the disaccharide concentration on the mean size of the unilamella vesicles. ► The effect of the extrusion speed on the mean size of the unilamella vesicles. ► Increasing mean diameter of ULVs with increasing disaccharide concentration. ► Decreasing mean diameter of ULVs with increasing extrusion speed. ► Fabrication of the uniform sized ULVs in different disaccharide solutions and pure water.
