Abstract
There is disclosed a novel colloidal metal dispersion in which colloidal particles of a metal are protected by specific polymers including hydrazide polymers, acrylic ester polymers and acrylamide polymers. The colloidal metal dispersion is highly stable, and the colloidal metal particles protected by such specific polymers can be easily and strongly bound to various amino group-containing compounds to give stable colloidal metal complexes, which have a wide variety of uses, such as the use as a solid catalyst, the use for the treatment and diagnosis of various diseases, the use for studying tissues of living bodies, the use for including mutation of microorganisms, etc.
