20080217445Method for producing fullerene suspension - The present invention provides a fullerene suspension and a method for producing a fullerene suspension having high dispersion stability without any chemical compound. Also, the fullerene suspension and its producing method makes it possible to be applied in various fields including the field of medical and pharmaceutical science and the field of foods and environment, in which the fullerene suspension obtained by the prior methods had not been applied. The fullerene is ground to form nanoparticles by irradiating a fullerene in a poor solvent with a laser. The pulse laser having a width of several-ten femtoseconds to several-hundred nanoseconds is appropriately applied.09-11-2008
20080237376Method of producing medicinal nanoparticle suspension - A method of producing a medicinal nanoparticle suspension is provided, wherein a medicinal ingredient added in a suspending solution is ground to form nanoparticles of the medicinal ingredient by irradiating the suspending solution with a laser. The process is implemented after adding a poorly water-soluble or water-insoluble medicinal ingredient of a drug in a poor solvent to form the suspending solution.10-02-2008
20100068794Cell Fusion Chip - (Problems) To provide a cell fusion chip, which allows to perform a cell fusion on a single chip, excels in the operating efficiency, does not require experience so much in cell feed or recovery, and has no risk of the contamination to the cells during the operation.03-18-2010
20100280580Biostimulation Apparatus, Gene Control Apparatus, and Muscle-Related Disorder Therapeutic Apparatus - A biostimulation apparatus of the present invention includes a laser oscillator for oscillating an ultra short pulsed laser beam and an optical system for focusing the ultra short pulsed laser beam, wherein the ultra short pulsed laser beam is focused by the optical system at a target portion of a living subject to cause the target portion to be irradiated with the laser beam to stimulate an acupuncture point, and wherein the target portion is either the acupuncture point or its periphery.11-04-2010
