Abstract
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.
