Localized or propagative Surface Plasmon Resonances (SPR) are at today widely investigated and
used for enhanced optical spectroscopy and optical (bio-)sensing. Among different techniques
used for the synthesis of metal nanomaterials, Pulsed Laser Ablation in Liquids (PLAL) appears one
of the most promising in terms of bio-compatibility and versatility, allowing the green synthesis of
a large gamma of metal nanoparticles (NPs) and metal-dielectric nanocomposites (NCs). After a
general introduction on the concepts of SPR resonances and state of art of PLAL, the talk will be
focused on the recent advances on the synthesis and applications of colloidal dispersions of Metal-
Carbynoid NCs by PLAL, followed by a description of the potentialities of SPR spectroscopy in the
all optical characterization of metal nanoparticles.
