Dendrimer-Based Coatings on a Photonic Crystal Surface for Ultra-Sensitive Small Molecule Detection

We propose and demonstrate dendrimer-based coatings for a sensitive biochip surface that enhance the high-performance sorption of small molecules (i.e., biomolecules with low molecular weights) and the sensitivity of a label-free, real-time photonic crysta ...

Photo- and Thermally- induced Effects on the Absorption Spectroscopy of Au/SiO2 and Au/TiO2 Core-shell Nanoparticles

Lijie Wang

Electrons generated by Landau damping of the plasmon excitation on gold nanoparticles that can be injected into an adjacent semiconductor e.g. anatase TiO2, enhancing the light harvesting capabilities of solar energy conversion devices. The understanding o ...

Porter le temps: mémoires urbaines du Locle et de la Chaux-de-Fonds

Florence Graezer Bideau

In our memory-obsessed time, cities have become places for the elaboration of images of the past that serve as a background for understanding, legitimizing, or contesting urban transformations. How are these cultural representations produced? How are they ...

Electrolyte-gated carbon nanotube field-effect transistorbased biosensors: Principles and applications

Nako Nakatsuka, Mattia Petrelli

Nowadays, there is a high demand for sensitive and selective real-time analytical methods suitable for a wide range of applications, from personalized telemedicine, drug discovery, food safety, and quality control, to defense, security, as well as environm ...

Assessing motorcycle taxi activity in Cameroon using GPS devices

Jérôme Chenal, Armel Firmin Kemajou Mbianda, Martí Bosch Padrós, Rémi Jaligot

The emergence of motorcycle taxis as a mode of urban transport in Africa can be seen as a bottom-up response to the larger problem of a demand that is not sufficiently met by public services. Transcending the debates regarding the relevance of this solutio ...

Electronic Structure-Dependent Surface Plasmon Resonance in Single Au-Fe Nanoalloys

Olivier Martin, Duncan Thomas Lindsay Alexander, Jérémy Butet, Gabriel David Bernasconi

The relationship between composition and plasmonic properties in noble metal nanoalloys is still largely unexplored. Yet, nanoalloys of noble metals, such as gold, with transition elements, such as iron, have unique properties and a number of potential app ...

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 ...

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 ...

Plasmon coupling in extended structures: Graphene superlattice nanoribbon arrays

Hatice Altug, Daniel Rodrigo Lopez

Interaction between localized plasmons in isolated proximal nanostructures is a well-studied phenomenon. Here we explore plasmon-plasmon interactions in connected extended systems. Such systems can now be easily produced experimentally using graphene. Howe ...

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 ...
