The following conclusions were able to be obtained as a result of experimenting for the purpose of clarifying the optimal operation conditions for producing a lipid bilayer (liposome) by being made from phosphatide by using the supercritical fluid of carbon dioxide, and moving the produced liposome in the arbitrary directions, 1) In order to obtain the small liposome of particle diameter, pressure was heightened at the temperature near a critical point, for example, the conditions of 35 degrees C and 12MPa were the optimal. 2) This was able to be driven by applying induced electromotive force to the liposome which made titanium oxide hold.
