Abstract
An object of the present invention is to provide a metal particle with which a highly-sensitive testing method can be conducted, and a testing method using such metal particle. The present invention provides a metal particle, which is produced by coating a metal particle labeled with a molecule binding to an analyte with a mixture of two or more types of water-soluble polymer having a mercapto group, a dithiol group or a sulfide group and differing in molecular weight.
