Surface-enhanced Raman scattering for the metal particles and molecular sensing

摘要

By controlled by control of the distance between the particles the enhanced electric field strength, particularly in the [challenge]-enhanced Raman scattering for metal nanoparticles, to grant the Raman scattering characteristics very strong, providing a Raman scattering sensing with high sensitivity. By linking through the organic molecule [SOLUTION] metal nanoparticles, and a metal nanoparticle aggregates coupled to a predetermined distance between the metal nanoparticles next to each metal nanoparticles of 10 to 3 , said population coalescing molecular sensing metal and molecular sensing metal nanoparticle material is one which is constituted by including a Raman active molecule in an electric field applied thereto, emit Raman scattered light is enhanced from the Raman active molecules in the enhanced electric field molecular sensing using the molecule sensing metal nanoparticle material and manufacturing method of the nanoparticle material.
