Cholesterol Drug delivery Liposome Polyethylene glycol Polymerization Liposomes are self-assembled vesicles consisting of a spherical bilayer structure surrounding an aqueous core domain [ 1 ]. Liposomes showed characteristics such as biocompatibility, biodegradability and low toxicity, where they can be affected by changing size, lipid composition and physical characteristics [ 2 ]. Depending on the preparation procedures, liposome sizes differ in the range of 20 nm to several microns. Small unilamellar liposomes may be produced by high-intensity ultra-sonication or high-pressure homogenization [ 3 , 4 ]. Liposomes have been widely used as drug carriers due to their structural versatility in terms of ...
