  • Patent number: 8309689
    Abstract: The invention relates to a simple and high yield process for producing a regenerated silk fibroin which does not need dialysis. Particularly, a process of the invention is characterized in that the silk fibroin is precipitated by applying a shear stress and/or changing the solvent power of the fibroin solution. The process of the invention simplifies the process of producing silk fibroin and greatly shortens the process time to 1 to 2 hours, whereas the conventional dialysis process is complex and needs around 2 to 3 days. In addition to reducing the time needed, the process of the invention can increase productivity of silk fibroin by at least 8%.

  • Patent number: 8263048
    Abstract: The invention is directed to a calcium phosphate complex and the composition containing the same for oral care applications, in which the calcium phosphate complex is formed by chelating the ?-polyglutamic acid (?-PGA) with amorphous calcium phosphate (ACP). This complex can prevent crystallization of ACP and maintain its high solubility. The calcium phosphate complex has superior mucoadhesion properties, allowing it to remain in the mouth longer and offering effective buffering, by which dental caries can be alleviated and prevented.

  • Publication number: 20070231375
    Abstract: The present invention relates to a liposome combination, which wrapped hydrophilic drugs in water layer and wrapped hydrophobic drugs in lipid bilayer; hydrophobic drugs are photosensitizers. Using light with appropriate wavelength to activate the photosensitizer in the hydrophobic layer can result in the production of singlet oxygen and the free radical, and cause the oxidizing and breaking of the carbon chain of the phospholipid, and influences the stability of the liposome and the releases of the drug. The singlet oxygen and the free radical will attack the cancer cells at the same time as a result of combining the photodynamic- and chemo-effects.
