PURPOSE:To change membrane permeability reversibly according to a delicate change of pH by forming a nylon capsule that responds the pH by filling dedodecyl sodium phsphate in fine pores of a nylon capsule membrane. CONSTITUTION:The nylon capsule 1 is forme from a nylon capsule membrane 2. This membrane 2 is porous and the inside thereof is communicated with the outside through fine pores 3. This fine pore part 3 is filled with a bimolecular membrane forming compound 4 comprised of dodecyl phosphate. This bimolecular membrane forming compound 4 forms a bimolecular membrane, and a fluorescence probe 5 trapped in inner water phase is confined in the capsule and hardly scattered to the outside. However, when pH of the outside of the capsule changes to 2.5-2, the compound 4 forms and maintains hardly the bimolecular membrane, and the fluorescence probes 5 are scattered to the outer water phase as shown by the arrow A. |
