  Here, we propose an easy and robust strategy for the versatile preparation of
hybrid plasmonic nanopores by means of controlled deposition of single flakes
of MoS2 directly on top of metallic holes. The device is realized on silicon
nitride commercial membranes and can be further refined by TEM or FIB milling
to achieve the passing of molecules or nanometric particles through a pore.
Importantly, we show 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. Here,
we also demonstrate that the prepared 2D material can be decorated with
metallic nanoparticles that can couple their resonance with the nanopore
resonance to further enhance the electromagnetic field confinement at the
nanoscale level. This method can be applied to any gold nanopore with a high
level of reproducibility and parallelization; hence, it can pave the way to the
next generation of solid-state nanopores with plasmonic functionalities.
Moreover, the controlled/ordered integration of 2D materials on plasmonic
nanostructures opens a pathway towards new investigation of the following:
enhanced light emission; strong coupling from plasmonic hybrid structures; hot
electron generation; and sensors in general based on 2D materials. Nanopore
