Liposomes are bilayer vesicles composed of phospholipids as the main material, and were first discovered by Bangham, a British scientist. Liposome’s structure is similar to biofilm, also known as artificial biofilm, and is widely used to study the structure and function of biofilm. Liposome used as a drug carrier began in the early 1970s. Due to the advantages of biocompatibility, biodegradability, non-toxicity and non-immunogenicity, liposomes have rapidly developed as new drug dosage forms. After more than 40 years of research, there are currently 12 liposomal preparations on the market. The drugs involved include adriamycin hydrochloride, amphotericin, muramyl-tripeptide, paclitaxel, gentamicin, and cytosine arabinoside, etc. In addition, various types of liposomes are…
