Document Type and Number:
WIPO Patent Application WO/2023/027166
Kind Code:
A1
Abstract:
Provided are core-shell nanoparticles having a gold nanoshell and having high dispersion stability, and a method for manufacturing the core-shell nanoparticles. A method for manufacturing core-shell particles having, on the core particle surface, a gold nanoshell and a protective agent, the manufacturing method including: (a) a step for mixing a solution of core particles and a solution of gold nanoclusters; (b) a step for adding a protective agent and a reducing agent, stirring the components, and adding a gold complex to form a gold nanoshell on the surface of the core particles; and (c) a step for recovering the core-shell particles produced in step (b).
