Plasmonic biosensor

Filiz Yesilköy, Alexander Belushkin

The present invention relates to a plasmonic biosensor system. The system includes a nano-hole array device comprising at least one nano-hole array (NHA) including at least one or a plurality of nano holes (NH), an image sensor (A3) for capturing light pro ...

Gold Nanofilms at Liquid–Liquid Interfaces: An Emerging Platform for Redox Electrocatalysis, Nanoplasmonic Sensors, and Electrovariable Optics

Pekka Eero Peljo, Micheal Diarmaid Scanlon, Evgeny Smirnov, Thomas James Stockmann

The functionality of liquid–liquid interfaces formed between two immiscible electrolyte solutions (ITIES) can be markedly enhanced by modification with supramolecular assemblies or solid nanomaterials. The focus of this Review is recent progress involving ...

Less Is More: Enhancement of Second-Harmonic Generation from Metasurfaces by Reduced Nanoparticle Density

Olivier Martin, Jérémy Butet

We investigate optical second-harmonic generation (SHG) from metasurfaces where noncentrosymmetric V-shaped gold nanoparticles are ordered into regular array configurations. In contrast to expectations, a substantial enhancement of the SHG signal is observ ...

Quantifying the role of surface plasmon excitation and hot carrier transport in plasmonic devices

Giulia Tagliabue

Harnessing photoexcited “hot” carriers in metallic nanostructures could define a new phase of non-equilibrium optoelectronics for photodetection and photocatalysis. Surface plasmons are considered pivotal for enabling efficient operation of hot carrier dev ...

, , ,

We have fabricated homogeneous thin films of an alloy of Au and Ag, by annealing two consecutive deposited layers of Au and Ag. We have also successfully fabricated nanodisks and nanorods made of AuAg alloys by annealing the nanostructures at 300 degrees C ...

Mathematical analysis of plasmonic nanoparticles: the scalar case

Pierre Robert Maurice Millien

Localized surface plasmons are charge density oscillations confined to metallic nanoparticles. Excitation of localized surface plasmons by an electromagnetic field at an incident wavelength where resonance occurs results in a strong light scattering and an ...

Aptamer-based Field-Effect Biosensor for Tenofovir Detection

Giovanni De Micheli, Sandro Carrara

During medical treatment it is critical to maintain the circulatory concentration of drugs within their therapeutic range. A novel biosensor is presented in this work to address the lack of a reliable point-of-care drug monitoring system in the market. The ...

2017

In this paper, a plasmonic-photonic nanostructure has been introduced for efficient unidirectional coupling of free-space radiation to surface plasmon polariton (SPP) waves under normal illumination on a subwavelength slit. The structure consists of a conv ...

Plasmonic photo-current in freestanding monolayered gold nanoparticle membranes

Jürgen Brugger

We report on photo-current generation in freestanding monolayered gold nanoparticle membranes excited by using a focused laser beam. The absence of a substrate leads to a 50% increase of the photo-current at the surface plasmon resonance. This current is a ...
