Abstract

Disclosed is a device and method allowing a trace amount of a target substance to be detected. A metallic nanoparticle assembly structure is formed of metallic nanoparticles assembled together and modified with a host molecule allowing the target substance to specifically adhere thereto. A metallic nanorod is modified with a host molecule allowing the target substance to specifically adhere thereto. The metallic nanorod is conjugated to the metallic nanoparticle assembly structure by the target substance. An extinction spectrum of localized surface plasmon resonance or a surface enhanced Raman scattering (SERS) spectrum induced in the metallic nanoparticle assembly structure and the metallic nanostructure is measured with a spectroscope. The target substance is detected based on that spectrum.
