Metal nanoparticle array structure, device for producing same, and method for producing same

摘要

An object of the invention is to provide a metal nanoparticle array structure in which metal nanoparticle arrays are firmly bonded to the substrate thereof via chemical bonding or the like and in which the coverage with the metal nanoparticle arrays is high.;The problem can be solved by using a metal nanoparticle array structure 10 that comprises a substrate 1, a immobilizing layer 2 formed on one surface 1a of the substrate 1, and metal nanoparticle arrays 3 formed on one surface 2a of the immobilizing layer 2, wherein the metal nanoparticle arrays 3 are so arrayed that multiple metal nanoparticles 4 can be at regular intervals and the metal nanoparticles 4 are bonded to each other via the modifying part 5 arranged on a surface thereof while the metal nanoparticles 4 are immobilized on one surface 2a of the immobilizing layer 2 via chemical bonds.
