Hybridization of various metal nanoparticles with light-harvesting dyes was investigated. In addition to the conventional dye molecule, newly designed dyes including a multivalent-type molecule could be applied to the protocol for the spontaneous hybridization. Detailed investigations on these chemical events clearly demonstrated that the hybrid nanoparticles should compose of the gold nanoparticles at the core surrounded by the dye-clustering shells. Furthermore, accumulated results concerning hybridization of the organic dyes with other inorganic materials demonstrated the applicability to platinum and silver nanoparticles.
