Abstract
The present invention relates to a method for detecting a target analyte using a gold nanoparticle, comprising growing a copper crystal specifically on a gold nanoparticle by treating the gold nanoparticle with a solution comprising a copper ion, a polymer having a primary or secondary amine group, and a reducing agent, a composition for amplifying a signal used in the detection method above, and a kit for detecting a target analyte comprising the composition for amplifying a signal above.
