Beaming of Helical Light from Plasmonic Vortices via Adiabatically Tapered Nanotip
TLDR
The proposed physical model, backed up by the numerical study, brings about an optimized structure that is fabricated by using a highly reproducible secondary electron lithography technique that excellently agree with the theoretically predicted far-field distributions.

Hybrid plasmonic nanostructures based on controlled integration of MoS2 flakes on metallic nanoholes.
TLDR
It is shown that the plasmonic enhancement provided by the nanohole is strongly accumulated in the 2D nanopore, thus representing an ideal system for single-molecule sensing and sequencing in a flow-through configuration.

Focusing dynamics on circular distributed tapered metallic waveguides by means of plasmonic vortex lenses.
TLDR
3D simulations show that by acting on the topological charge of the plasmonic vortex the electric field charge distribution at the tips apex can be controlled accordingly to the input electric field phase distribution.

Plasmonic nanopores for single-molecule detection and manipulation: towards sequencing applications.
TLDR
The use of plasmonic nanopores to engineer electromagnetic fields around a nanopore sensor allows for enhanced optical spectroscopies, local control over temperature, thermophoresis of molecules and ions to/from the sensor, and trapping of entities.
