Technique for Characterising Liposome Formulated Drugs

Nanoparticles including liposomes are increasingly used for delivery of drug molecules. During formulation of a liposome around a drug particle, a relatively large amount of free drug may remain unencapsulated and therefore not available for drug delivery via the liposomal carrier. For formulation groups adopting this drug delivery methodology it is important to quantify the amount of free versus encapsulated drug in a product in order to accurately determine the delivered dose of drug to a patient.
