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.

Abstract: The disclosed technology relates to methods, apparatuses and systems for detecting molecules using surface plasmon resonance techniques, and more particularly to surface plasmon resonance techniques that employ metal nanoparticles formed on substrates. In one aspect, method of making a layer of metallic nanoparticles includes providing a liquid composition comprising a binder polymer and a solvent and at least partially immersing, into the liquid composition, an article comprising a polymeric surface, wherein the polymeric surface comprises a polymeric material and does not comprise an inorganic glass or crystalline material. The method additionally includes applying a gas phase plasma to the liquid composition to facilitate chemical reactions between the binder polymer and the polymeric material of the polymeric surface to form a binder layer on the polymeric surface of the article.

Abstract: The present invention relates to a spectroscopic sensor and a method for manufacturing the same. A spectroscopic sensor according to one embodiment of the present invention includes a fiber layer including a plurality of flexible fibers and a surface plasmon active layer formed on the surface of the fibers. The surface plasmon active layer is densely formed and enables highly reliable spectroscopy. The fiber layer is flexible and facilitates the collection of a target sample.
