Outline of Final Research Achievements

We have developed an excellent purification method for functional nanoparticles using cartridges or HPLC. In the HPLC method, discrimination was based on the surface potential of the nanoparticles and particles were separated based on the magnitude of the zeta potential. A technique using a solid-phase extraction cartridge enabled purification in a short period of time. By using these methods, it became possible to obtain uniform nanoparticles.
