3. A method of inserting deoxyribonucleic acid into a living cell, which comprises;
-
(1) providing a mixture of a vesicle wall forming compound in organic solvent and an aqueous mixture of the deoxyribonucleic acid material to be encapsulated, the ratio of organic phase to aqueous phase being that which will produce a water-in-oil emulsion; (2) forming a homogeneous water-in-oil emulsion of said mixture, of the character produced by ultrasonic radiation; (3) removing organic solvent from the emulsion, whereby a mixture is obtained having a gel-like character; (4) converting the gel-like mixture to a suspension of synthetic, oligolamellar vesicles encapsulating the deoxyribonucleic acid material; and bringing the encapsulated material into contact with the cell, whereby insertion occurs.
