Abstract
A method for manufacturing modified metal nanoparticles includes steps as follows. Metal nanoparticles are provided, wherein each of the metal nanoparticles is a gold nanoparticle or a silver nanoparticle. An ascorbic acid solution is provided, wherein the ascorbic acid solution includes ascorbic acid molecules and/or ascorbic acid ions. A surface modification step is conducted, wherein the metal nanoparticles and the ascorbic acid solution are mixed, such that surfaces of the metal nanoparticles are modified by the ascorbic acid molecules and/or ascorbic acid ions to obtain the modified metal nanoparticles.
