摘要:
A suspension of heterogeneous size liposomes is passed through a polymer filter having a web-like construction providing a network of interconnected, tortuous-path capillary pores, and a membrane thickness of at least about 100 microns. The processed liposomes have a selected average size less than about 0.4 microns, and a narrow size distribution.
