Liposome Nanoparticles Synthesis

Liposomes were discovered in the 1960s. These hollow nanoparticles are phospholipid vesicles consisting of at least one lipid bilayer. This bilayer is usually composed of amphiphilicphospholipids that have a hydrophilic phosphate head and a hydrophobic tail consisting of two fatty acid chains. This structural feature has facilitated liposomes’ applications, including their use as artificial cell membranes, carriers for drug delivery systems, encapsulating agents forfood ingredients, and analytical tools.
