Size and Zeta Potential of Liposomes

liposome is a spherical vesicle having at least one lipid bilayer used for drug delivery. Most liposomes are measured using a DLS system like the Nicomp. But larger liposomes have been successfully analyzed using the AccuSizer SPOS system.

Liposomes Defined

Liposomes are bilayer vesicles routinely used in the pharmaceutical industry as a drug delivery system for transport of chemotherapeutic drugs to the tumor area. They are composed of phospholipids that have a polar end attached to a non-polar chain that self assemble into bilayer vesicles with the polar ends facing the aqueous medium and non-polar…
