  • 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.

  • Publication number: 20050189498
    Abstract: An irradiation apparatus for a photodynamic treatment. The irradiation apparatus includes a main body, a high power light emitting element, an optical lens assembly and an optical fiber. The high power light emitting element is disposed on the main body to output light. The optical lens assembly is adjacent to the high power light emitting element and disposed on the main body to receive the light from the high power light emitting element. The optical fiber has an input end and an output end. The input end is coupled to the optical lens assembly to receive and transmit the light from the optical lens assembly.
