Definition of the Topic
Metal nanoparticles present peculiar optical properties at their surface plasmon resonances, such as marked optical absorption, enhanced near-field and scattering to the far-field. From works involving the fabrication of tailor-made metal nanoparticles together with the accurate characterization of their optical response, it has been demonstrated that the plasmon-related optical features are sensitive to the size, shape, and environment of the nanoparticles. Such sensitivity is of
