Galvanic Replacement Reaction to prepare nanoporous Aluminum for UV plasmonics
Denis Garoli, Giorgia Giovannini, Sandro Cattarin +9
Plasmonics applications have been extending into the ultraviolet region of the electromagnetic spectrum. Unfortunately the commonly used noble metals have intrinsic optical propert…
Electrophoretic deposition of WS2 flakes on nanoholes arrays. Role of the used suspension medium
Dario Mosconi, Giorgia Giovannini, Nicolo Maccaferri +4
Here we optimized the electrophoretic deposition process for the fabrication of WS2 plasmonic nanohole integrated structures. We showed how the conditions used for the site selecti…
Chemically-controlled self-assembly of hybrid plasmonic nanopores on graphene
Giorgia Giovannini, Matteo Ardini, Nicolo Maccaferri +6
Thanks to the spontaneous interaction between noble metals and biological scaffolds, nanomaterials with unique features can be achieved following relatively straightforward and cos…
SERS discrimination of single amino acid residue in single peptide by plasmonic nanocavities
Jian-An Huang, Mansoureh Z. Mousavi, Giorgia Giovannini +4
Surface-enhanced Raman spectroscopy (SERS) is a sensitive label-free optical method that can provide fingerprint Raman spectra of biomolecules such as DNA, amino acids and proteins…
Nanoporous Aluminum-Magnesium Alloy for UV enhanced spectroscopy
Paolo Ponzellini, Giorgia Giovannini, Sandro Cattarin +11
We report the first preparation of nanoporous Al-Mg alloy films by selective dissolution of Mg from a Mg-rich AlxMg1-x alloy. We show how to tune the stoichiometry, the porosity an…
Single-molecule DNA Bases Discrimination in Oligonucleotides by Controllable Trapping in Plasmonic Nanoholes
Jian-An Huang, Mansoureh Z. Mousavi, Yingqi Zhao +6
Surface-enhanced Raman spectroscopy (SERS) sensing of DNA sequences by plasmonic nanopores could pave a way to new generation single-molecule sequencing platforms. The SERS discrim…
