Planar Optical Nanoantennas Resolve Cholesterol-Dependent Nanoscale Heterogeneities in the Plasma Membrane of Living Cells

Jürgen Brugger, Valentin Flauraud, Pamina Winkler, Raju Regmi

Optical nanoantennas can efficiently confine light into nanoscopic hotspots, enabling single-molecule detection sensitivity at biological relevant conditions. This innovative approach to breach the diffraction limit offers a versatile platform to investiga ...

Transient Nanoscopic Phase Separation in Biological Lipid Membranes Resolved by Planar Plasmonic Antennas

Jürgen Brugger, Valentin Flauraud, Pamina Winkler, Raju Regmi

Nanoscale membrane assemblies of sphingolipids, cholesterol, and certain proteins, also known as lipid rafts, play a crucial role in facilitating a broad range of important cell functions. Whereas on living cell membranes lipid rafts have been postulated t ...

Growth Of Organic Semiconductor Thin Films with Multi-Micron Domain Size and Fabrication of Organic Transistors Using a Stencil Nanosieve

Jürgen Brugger, Shenqi Xie, Valentin Flauraud

To grow small molecule semiconductor thin films with domain size larger than modern-day device sizes, we evaporate the material through a dense array of small apertures, called a stencil nanosieve. The aperture size of 0.5 μm results in low nucleation dens ...

Silicon nanostructures for bright field full color prints

Jürgen Brugger, Valentin Flauraud, Miguel Arnold Reyes

Nanoscale color printing has recently emerged as a unique alternative to traditional pigments by providing record spatial resolution, angular independent, durable and single material colors. Widely based on plasmonic nanostructures, numerous efforts in the ...

Novel manufacturing methods for optical antennas : controlling light down to the single nanometer scale

Valentin Flauraud

The resonant excitation of free electrons in metallic nanostructures enables extreme near field intensities along with a deep sub-wavelength localization of the electromagnetic energy. This has been exploited to enhance light-matter interaction down to the ...

Mode Evolution in Strongly Coupled Plasmonic Dolmens Fabricated by Templated Assembly

Jürgen Brugger, Olivier Martin, Duncan Thomas Lindsay Alexander, Massimo Mastrangeli, Valentin Flauraud, Jérémy Butet, Gabriel David Bernasconi

Plasmonic antennas have enabled a wealth of applications that exploit tailored near-fields and radiative properties, further endowed by the bespoke interactions of multiple resonant building blocks. Specifically, when the interparticle distances are reduce ...

Synthesis of superposition shape images by light interacting with layers of lenslets

Jürgen Brugger, Roger Hersch, Thomas Walger, Valentin Flauraud, Théophane Besson

The present invention describes methods and apparatuses for creating superposition shape images by superposed base and revealing layers of lenslet gratings. The superposition shape images form a message recognizable by a human observer or by an image acqui ...

Electron Energy-Loss Spectroscopy of Coupled Plasmonic Systems: Beyond the Standard Electron Perspective

Jürgen Brugger, Olivier Martin, Jérémy Butet, Gabriel David Bernasconi, Valentin Flauraud

Electron energy-loss spectroscopy (EELS) has become an experimental method of choice for the investigation of localized surface plasmon resonances, allowing the simultaneous mapping of the associated field distributions and their resonant energies with a n ...

Arrays of Pentacene Single Crystals by Stencil Evaporation

Jürgen Brugger, Shenqi Xie, Valentin Flauraud

In order to realize high-performance organic thin-film transistors (TFT), two parameters of the organic semiconducting layer are desired: single crystallinity for high mobility and patterning for low off currents. High-quality single crystals can be fabric ...
