Abstract
The present invention provides methods and systems for producing liposomes by filtration. The methods include passing a heated lipid suspension through a filter assembly comprising two or more filters connected in series, wherein an orifice is disposed between adjacent filters. The methods and systems can produce liposomes having an average diameter that is less than half the diameter of the filter pores. Further, the methods and systems can produce liposomes with <100 nm average diameter, even when the liposomes comprise at least 30% sterol.
