1-11. (canceled)
A nanocolloidal platinum dispersion comprising nanocolloidal platinum and a polyacrylic acid salt, said nanocolloidal platinum having an average particle size of 1-5 nm, 90% or more of said nanocolloidal platinum having a particle size in a range of 0.1-10 nmn.
A method for producing a nanocolloidal platinum dispersion comprising the steps of refluxing a solution comprising a platinum salt, a polyacrylic acid salt, an alcohol and water, evaporating said alcohol and said water from the resultant dispersion to such an extent that part of them remain, adding alcohol to said dispersion, and then evaporating alcohol and water again.
A nanocolloidal platinum-containing drink comprising a nanocolloidal platinum dispersion, which comprises nanocolloidal platinum and a polyacrylic acid salt, said nanocolloidal platinum having an average particle size of 1-5 nm, 90% or more of said nanocolloidal platinum having a particle size in a range of 0.1-10 nm.
