Features of Liposomes

Because of their characteristic bilayer structure, liposomes can cross the cell membrane, so they can be used as a means of transportation of nutrients and some types of drugs. After reaching a specific predetermined position in the body, the lipid will rupture or decompose, thus releasing potentially lifesaving drugs.

At present, many researchers have studied and worked on liposomes, but only a small number of liposomal products have been approved for human use. This may be due to many reasons, such as high cost of liposome production, especially large-scale production, toxicity of some liposome formulations, relatively short half-life, instability, low solubility, encapsulation of low molecules and compounds into vesicles, and sometimes oxidation and hydrolysis of phospholipids, etc.
