## Abstract

The present invention relates to a method for manufacturing a nanoparticle array, a surface plasmon resonance-based sensor, and a method for analyzing using the same. According to one embodiment of the present invention, after a mixed solution of an ionized binder and conductive nanoparticles is prepared, a substrate is dipped into the mixed solution. Thereafter, by applying an electric field to the mixed solution into which the substrate is dipped so as to induce coating of the conductive nanoparticles on the substrate, it is possible to manufacture, by a wet method, a nanoparticle array in which the conductive nanoparticles are quickly coated on the substrate with high density.
