title: Particle control of emulsion by membrane emulsification and its applications.
abstract: Particle-size control of emulsion is very important for maintaining stability and giving emulsions new functional roles. Porous glass membrane, prepared by phase separation of a glass composition, is available as an emulsifying element, from which, one can obtain monodispersed emulsion with different particle sizes, and useful water/oil/water (W/O/W) emulsion in very high yield. The authors have called this new technology 'membrane emulsification'. Applications of membrane emulsification technology to drug delivery systems were carried out under cooperative research with Miyazaki Medical College. It was found that the clinical administration of a W/O/W drug emulsion that encapsulated an anticancer drug in its inner droplets was surprisingly effective for both terminal and multiple nodules of hepatocellular carcinoma when the drug was injected to damaged liver through a catheter inserted in the hepatic artery. Other applications have been tried and developed elsewhere.
