  • Preparation of nanoliposome-encapsulating proteins and protein-encapsulated nanoliposome
    Patent number: 7951396
    Abstract: Preparing a nanoliposome for encapsulating a protein includes preparing a dispersion by dispersing a phospholipid in an aqueous solution containing the protein, applying a shearing force to the dispersion; adding an additional amount of the phospholipid to the result of the step of applying the shearing force to the dispersion and then applying a shearing force higher than that of the step of applying the shearing force to the dispersion, and repeating the step of adding the additional amount of the phospholipid and applying the higher shearing force with an additional amount of the phospholipid and a shearing force higher than the prior step to obtain a nanoliposome having a desired diameter and encapsulation efficiency.
