Nanoparticle body, composite containing nanoparticle bodies, and method for forming polymer membrane containing nanoparticle body

Abstract

A nanoparticle body comprising: a metallic nanoparticle; a polymer film covering a surface of the metallic nanoparticle; a specifically bondable substance that specifically bonds to a test substance in a specimen; and a fluorescent substance labeled on a surface of the polymer film or on the specifically bondable substance, wherein the fluorescent substance is excited by light having a luminous wavelength of plasmon resonance in a composite in which two or more of the nanoparticle body are bonded together with the test substance interposed therebetween.

Dependencies are inferred from the claim text.
