Nanophotonics: the ubiquitous science. Nanophotonics in the last years is showing clearly its inclusive nature. Several disciplines are taking advantages in using novel tools derived from the astonishing progress in Nanophotonics, for exploring novel fundamental properties of materials on different length scale. The optical methods, both experimental and theoretical, are ubiquitous in several fields facilitating the development of a common language even for disciplines considered far, just a few years ago. This third edition of NANOP confirms a broad topics list with the aim of bridging the macro with the molecular world.
