    Abstract: PURPOSE: A production method of polymerized liposome is provided to polymerize by only controlling the pH from 6.4 to 8.4. CONSTITUTION: A production method of polymerized liposome has the steps of: dissolving the 1,2-bis(12-(lipolyoxy)dedecanoyl)-sn-glycero-3-phosphocholine in chloroform; removing the solvent and drying in a vacuum state for about 1 hr. to form a thin membrane; adding the solution of pH 6.4 in a test-tube having the thin membrane; vortex mixing after 30min. to obtain the liposome solution of a state of semi-transparent; passing the liposome solution of a state of semi-transparent through an extruder sustained at 40°C into a filter of a specific size with a pressure of nitrogen or argon gas; keeping the pH to 8.4 and agitating for 1 day at a room temperature; keeping the pH to 6.4.
