The composites include noble metal nanoparticles having a layer of linker molecules being bound to the surface of the noble metal nanoparticle and a layer of dye molecules bound to the layer of linker molecules. The dye molecules are selected such that they form an ordered structure that exhibits a collective absorption band shift, compared to the individual dye molecule, when bound to the noble metal nanoparticle. This structure is encapsulated in a stabilizing coating layer forming a multi-shell structure with properties suitable for biosensing and other detection applications which exhibit enhanced Raman scattering compared to nanoparticles having dye molecules bound thereto not in the ordered structure."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Encapsulated dye coated noble metal nanoparticles with increased surface enhanced Raman scattering properties as contrast agents","description":"The present disclosure provides semiconductor-metal composite nanoparticles with optical properties that are superior to those of pure materials for use as contrast agents.
