20090202650 | METHODS OF TREATING CANCERS - A method of treating cancer. The method includes introducing an effective amount of an oxidative catalyzing agent including titanium oxide, zinc oxide, zirconium oxide, tungsten oxide or tin oxide into a biological entity, and irradiating the biological entity with a ray. The oxidative catalyzing agent produces hydroxyl or hydrogen peroxide radicals after irradiation with the ray thereon. | 08-13-2009 |
20100248297 | PARTICLES AND MANUFACTURING METHODS THEREOF - Particles and manufacturing methods thereof are provided. The manufacturing method of the particle includes providing a precursor solution containing a precursor dissolved in a solution, and irradiating the precursor solution with a high energy and high flux radiation beam to convert the precursor to nano-particles. Particles with desired dispersion, shape, and size are manufactured without adding a stabilizer or surfactant to the precursor solution. | 09-30-2010 |
20110044900 | METHOD FOR TREATING AND/OR DIAGNOSING TUMOR BY GOLD PARTICLES COATED WITH A POLYMER - A method for treating and/or diagnosing a tumor is provided. The method includes administrating an effective amount of gold particles to a subject in need thereof, and observing the distribution of the gold particles in the subject, wherein the gold particles are coated with a polymer, and the gold particle has a size of about 6.1±1.9 nm. | 02-24-2011 |
20110288409 | Imaging of Biological Structures - Images of blood vessels of a body are obtained by injecting a refraction enhancement contrast agent into the blood vessels to increase a difference in refractive indices of the blood vessels and surrounding material. The blood vessels are irradiated with a penetrating radiation, and an image of the blood vessels is generated based on detected radiation. The image has visible edge enhancement features indicating boundaries of the blood vessels. | 11-24-2011 |
