Structural heterogeneity of the ion and lipid channel TMEM16F

Transmembrane protein 16 F (TMEM16F) is a Ca2+-activated homodimer which functions as an ion channel and a phospholipid scramblase. Despite the availability of several TMEM16F cryogenic electron microscopy (cryo-EM) structures, the mechanism of activation ...

Prospects of Observing Ionic Coulomb Blockade in Artificial Ion Confinements

Aleksandra Radenovic, Andrey Chernev, Sanjin Marion

Nanofluidics encompasses a wide range of advanced approaches to study charge and mass transport at the nanoscale. Modern technologies allow us to develop and improve artificial nanofluidic platforms that confine ions in a way similar to single-ion channels ...

Towards artificial mechanosensing

Aleksandra Radenovic, Sanjin Marion

Carbon nanotubes with single-digit diameter embedded in a solid artificial membrane show pressure-sensitive ionic conductance that is similar to the mechanically activated currents of biological ion channels. ...

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 ...

Mapping the function of neuronal ion channels in model and experiment

Rajnish Ranjan, Alexander Kevin Seeholzer, Tim Vogels, William Francis Podlaski

Ion channel models are the building blocks of computational neuron models. Their biological fidelity is therefore crucial for the interpretation of simulations. However, the number of published models, and the lack of standardization, make the comparison o ...

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 ...

Plasmonic photoconductance in free-standing monolayered gold nanoparticle membranes

Jürgen Brugger

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

The Selenga River delta: a geochemical barrier protecting Lake Baikal waters

Yosef Akhtman, Galina Shinkareva, Mikhail Tarasov

The protection of Lake Baikal and the planning of water management measures in the Selenga River Basin require a comprehensive understanding of the current state and functioning of the delta’s ecosystem and hydrogeo- chemical processes. This is particularl ...

First demonstration of plasmonic GaN quantum cascade detectors with enhanced efficiency at normal incidence

Nicolas Grandjean, Etienne François Olivier Giraud

We have designed, fabricated and measured the first plasmon-assisted normal incidence GaN/AlN quantum cascade detector (QCD) making use of the surface plasmon resonance of a two-dimensional nanohole Au array integrated on top of the detector absorption reg ...

LSPR Chip for Parallel, Rapid, and Sensitive Detection of Cancer Markers in Serum

Sebastian Maerkl, Jose Luis Garcia Cordero

Label-free biosensing based on metallic nano-particles supporting localized surface plasmon resonances (LSPR) has recently received growing interest (Anker, J. N., et al. Nat. Mater. 2008, 7, 442-453). Besides its competitive sensitivity (Yonzon, C. R., et ...
