Electromagnetic fields near plasmonic wedges.

Optics letters

Disfani MR, Abrishamian MS, Berini P.
PMID: 22627531
Opt Lett. 2012 May 15;37(10):1667-9. doi: 10.1364/OL.37.001667.

The behavior of electromagnetic fields near the edge of a plasmonic wedge is investigated. We study the scattering properties, field divergence, and field enhancement near an Au wedge bounded by SiO2 upon illumination by TM-polarized light using hypersingular integral...

A hybrid silicon-PDMS optofluidic platform for sensing applications.

Biomed Opt Express. 2014 Jan 09;5(2):417-26. doi: 10.1364/BOE.5.000417. eCollection 2014 Feb 01.

A hybrid silicon-poly(dimethysiloxane) (PDMS) optofluidic platform for lab-on-a-chip applications is proposed. A liquid-core waveguide with a self-aligned solid-core waveguide and a microfluidic device are integrated with a multilayer approach, resulting in a three-dimensional device assembly. The optofluidic layer was...

Continuous EEG-fMRI in Pre-Surgical Evaluation of a Patient with Symptomatic Seizures: Bold Activation Linked to Interictal Epileptic Discharges Caused by Cavernoma.

Neuroradiol J. 2008 Apr 07;21(2):183-91. doi: 10.1177/197140090802100205. Epub 2008 Apr 07.

We used continuous electroencephalography-functional magnetic resonance imaging (EEG-fMRI) to identify the linkage between the "epileptogenic" and the "irritative" area in a patient with symptomatic epilepsy (cavernoma, previously diagnosed and surgically treated), i.e. a patient with a well known "epileptogenic...

Ordered gold nanoparticle arrays on glass and their characterization.

Journal of colloid and interface science

Yuan J, Hajebifard A, George C, Berini P, Zou S.

J Colloid Interface Sci. 2013 Nov 15;410:1-10. doi: 10.1016/j.jcis.2013.07.070. Epub 2013 Aug 12.

Using self-assembly of block copolymer micelle loaded metal precursors, combined with a seeding growth route, we have developed a novel approach to create ordered metal nanoparticle (NP) arrays of controllable size over large areas (~80 mm(2)) on solid substrates....

Visible light driven plasmonic photochemistry on nano-textured silver.

Physical chemistry chemical physics : PCCP

Walia J, Guay JM, Krupin O, Variola F, Berini P, Weck A.
PMID: 29199757
Phys Chem Chem Phys. 2017 Dec 20;20(1):238-246. doi: 10.1039/c7cp07024a.

Plasmon assisted generation of silver sulfate from dodecanethiol is demonstrated on a nano-textured silver substrate with a strong surface plasmon resonance in the visible range. The observed photo-physical processes are attributed to hot charge carriers that are generated from...

Proposal of Brillouin optical frequency-domain reflectometry (BOFDR).

Optics express

Minardo A, Bernini R, Ruiz-Lombera R, Mirapeix J, Lopez-Higuera JM, Zeni L.
PMID: 28059384
Opt Express. 2016 Dec 26;24(26):29994-30001. doi: 10.1364/OE.24.029994.

We demonstrate a Brillouin optical frequency-domain reflectometry (BOFDR) technique, which can measure the strain and/or temperature along an optical fiber with one-end access, by detecting the spontaneous Brillouin scattering from a sinusoidally modulated pump light. Compared to the Brillouin...

Laser-induced plasmonic colours on metals.

Nature communications

Guay JM, Calà Lesina A, Côté G, Charron M, Poitras D, Ramunno L, Berini P, Weck A.
PMID: 28719576
Nat Commun. 2017 Jul 18;8:16095. doi: 10.1038/ncomms16095.

Plasmonic resonances in metallic nanoparticles have been used since antiquity to colour glasses. The use of metal nanostructures for surface colourization has attracted considerable interest following recent developments in plasmonics. However, current top-down colourization methods are not ideally suited...

Hybrid Therapy for Atrial Fibrillation: where the Knife meets the Catheter.

Journal of atrial fibrillation

Curnis A, Bisleri G, Bontempi L, Salghetti F, Cerini M, Lipari A, Pagnoni C, Vassanelli F, Muneretto C.
PMID: 28496850
J Atr Fibrillation. 2013 Jun 30;6(1):775. doi: 10.4022/jafib.775. eCollection 2013.

During the past decades there has been a consistent evolution of both surgical and catheter-based techniques for the treatment of stand-alone atrial fibrillation, as alternatives or in combination with anti-arrhythmic drugs. Transcatheter ablation has significantly improved outcomes, despite often...
