  • Patent number: 9005654
    Abstract: The present invention provides apparatus and processes for producing liposomes. By providing a buffer solution in a first reservoir, and a lipid solution in a second reservoir, continuously diluting the lipid solution with the buffer solution in a mixing chamber produces a liposome. A therapeutic agent, such as nucleic acid, is included in one of the buffer solution or the lipid solution. Upon mixing a liposome encapsulating the therapeutic product is substantially instantaneously formed. Thereafter the liposome solution formed is immediately diluted with buffer solution to enhance homogeneity and maintain small particle size.
