Monodispersed Chitosan Microspheres Shirasu Porous Glass Membrane Emulsification Mechanisms Microsphere |
Résumé : |
The Shirasu porous glass (SPG) membrane emulsification technique was employed for the preparation of monodispersed chitosan microspheres with the diameter controlled to be in the range from submicrometers to 10 μm. Three preparation methods were used in this study: (1) a cross-linking method with glutaraldehyde, (2) an interaction method with alginate, and (3) a drying-in-liquid method with aqueous sodium hydroxide medium. In every preparation method, various SPG membranes with different pore sizes were used for microsphere formation, and the fabrication mechanism for the microspheres was elucidated. It was successfully shown from these detailed investigations that the average diameters of the chitosan microspheres were controlled in the range of submicrometer to 10 μm by the pore sizes of the SPG membranes for preparing chitosan emulsions by method 1, alginate emulsions by method 2, or chitosan emulsions by method 3. |
