Top-down fabrication allows for the realization of morphologically controlled micro/nano devices down to few nanometers scale. We investigate a number of applications based on this fabrication technique, with special emphasis towards nanoplasmonics. In particular, we shall focus on quasi-2D and 3D SERS devices, to move on with TERS structures especially designed to provide superfocusing characteristic. This feature, besides having tremendous impact in improving the TERS spatial resolution, is at the core of a new kind of nanoscopy technique based on hot-electrons transfer. Finally, we shall provide a flavor of a new paradigm, namely the magnetic field enhancement and concentration from 2D SERS-like nanodevices.
