Abstract
With this invention, in a nanoparticle production method, wherein nanoparticles are produced by irradiating a laser light irradiation portionof a to-be-treated liquidwith a laser light, in which suspended particles are suspended, to pulverize the suspended particles in laser light irradiation portion, laser light irradiation portionof to-be-treated liquidis cooled. In this case, by the cooling of to-be-treated liquid, the respective suspended particles are cooled in their entireties. When the portionof this to-be-treated liquidis irradiated with the laser light, the laser light is absorbed at the surfaces of the suspended particles at portion. Since to-be-treated liquidis cooled during this process, significant temperature differences arise between the interiors and surfaces of the suspended particles and between the surfaces of the suspended particles and the to-be-treated liquid at laser light irradiation portion, and highly efficient nanoparticulation is realized.
