Title:
METHOD FOR NANOPARTICLE PURIFICATION
Document Type and Number:
WIPO Patent Application WO/2016/136723
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a method for nanoparticle purification with which it is possible to safely obtain a large amount of nanoparticles in a short time as compared with conventional nanoparticle purification methods. The method for nanoparticle purification according to the present invention is a method for obtaining purified nanoparticles from a dispersion thereof in a solvent A used for synthesizing the nanoparticles. The method comprises: a mixing step in which the dispersion, a solvent B that is miscible with the solvent A, and a solvent C that forms two phases when coexistent with the solvent B are mixed; a concentration step in which the nanoparticles are concentrated in the phase of the solvent C; a cleaning step in which a third phase comprising the phase of the solvent C and the nanoparticles contained therein is formed; and a purification step in which the third phase is taken out and the solvent C is removed from the third phase.
