摘要

PROBLEM TO BE SOLVED: To provide metal nanoparticles having superior detection sensitivity as labeled materials at low cost.;SOLUTION: A compound having a chemical structure where one terminal includes a functional group to be stably coupled to the surface of a metal nanoparticle via the sulfur atoms of a sulfur compound, and the other terminal has a carboxyl group and an amino group at the carbon in the position thereof is used as a compound 3 for a surface modification agent and also a linker. A plurality of pieces of the metal nanoparticles 2 whose surfaces are modified using the compound are aggregated so as to be made into a cluster.;COPYRIGHT: (C)2011,JPO&INPIT
