PROBLEM TO BE SOLVED: To provide a novel manufacturing method of gold nanoparticle capable of precisely controlling particle size from seed crystal size (e.g. tens of nm) to 1 μm and avoiding aggregation with inhibiting a surface residual article.SOLUTION: There is provided a manufacturing method of gold nanoparticle including following processes. (1) a process for preparing a raw material gold nanoparticle dispersion. (2) a process for preparing a metal substrate having a coated layer capable of immobilizing the raw material gold nanoparticle on at least a part of surface, where the metal substrate contains a metal having lower reduction potential than gold. (3) a process for arranging the raw material gold nanoparticle dispersion on the coated layer of the metal substrate to grow gold nanoparticle.SELECTED DRAWING: None |
