Interessi di ricerca

Antonino’s research topics range within the field of nano-optics and plasmonics. In particular, he has been focused to the optimization of advanced characterization techniques such as surface- and tip- enhanced Raman spectroscopy (SERS and TERS) for the development of label-free sensors that allow the ultrasensitive detection of (bio)molecules and for chemical imaging of thin molecular films and nanostructured materials with nanoscale spatial resolution. Antonino is also interested in developing sensing techniques that combine SERS and optical forces to manipulate plasmon nanoparticles and create on-demand SERS-active aggregates directly in liquid. He has recently faced the microplastic issues employing Raman optical tweezers. This technique allow the control and simultaneous chemical identification in liquid at the level of the single nano-object has allowed the characterization of micro and nano plastics dispersed in water or complex matrices.

He is editor of the JEOS special issue PLASMONICA2023.
