Abstract:

We shall illustrate the fundamental role played by nanoplasmonics in a number of nanodevices showing different characteristics in terms of topological and material point of view, and oriented to different applications. In particular, we shall start by describing how superhydrophobicity can be used to go beyond the diffusion limit, hence allowing the realization of devices capable of detecting, in a very short time, an extremely small number of molecules [1,2]. We shall proceed by introducing 3D suspended devices which, similarly to the hydrophobic ones, can find suitable applications in the SERS field but, on the other hand, do not need to reproduce a superhydrophobic layout. Finally, by joining the concept of adiabatic compression and hot electrons, we shall demonstrate how nanoplasmonics can, once again, amaze us by allowing the realization of a new kind of nanoscopy [3].
