Orientation Dependence of Plasmonically Enhanced Spontaneous Emission

We computationally explore how the orientation of dipolar emitters placed near plasmonic nanostructures affects their radiative enhancement and spontaneous emission rate. We demonstrate that the expressions for these quantities show a subtle dependence on ...

Second-harmonic radiating imaging probes and harmonic holography

Demetri Psaltis, Ye Pu

Compared with other imaging probes such as fluorescent dyes and quantum dots, second-harmonic radiating imaging probes (SHRIMPs) provide a unique ultrafast, coherent optical contrast that is free of photobleaching and emission intermittency. Using the seco ...

An automated microreactor for semi-continuous biosensor measurements

Philippe Renaud, Harald Van Lintel, Nina Buffi, Jan Roelof van der Meer

Living bacteria or yeast cells are frequently used as bioreporters for the detection of specific chemical analytes or conditions of sample toxicity. In particular, bacteria or yeast equipped with synthetic gene circuitry that allows the production of a rel ...

Automated longitudinal monitoring of in vivo protein aggregation in neurodegenerative disease C. elegans models

Johan Auwerx, Martinus Gijs, Thomas Lehnert, Matteo Cornaglia, Laurent Mouchiroud, Vincenzo Sorrentino, Govindan Narayanan Krishnamani

Background: While many biological studies can be performed on cell-based systems, the investigation of molecular pathways related to complex human dysfunctions - e.g. neurodegenerative diseases - often requires long-term studies in animal models. The nemat ...

Nanoscopy in nonlinear scanning fluorescence imaging systems

Grégoire Pierre Jean Laporte

In the last 30 years, superresolution in optical microscopy has been a major field of research. During this time, different techniques have been created to break the diffraction limit in order to make observations at a nanometric scale. Given that optical ...

Drexhage’s Experiment for Sound

Romain Christophe Rémy Fleury

Drexhage’s seminal observation that spontaneous emission rates of fluorophores vary with distance from a mirror uncovered the fundamental notion that a source’s environment determines radiative linewidths and shifts. Further, this observation established a ...

Fluorescent Probes for Plasma Membrane Proteins Based on Nile Red

Efthymia Prifti

Fluorescent probes are very important in basic research and in medicine, because of their sensitivity, versatility and quantitative capabilities. They allow the imaging of tissues or cellular compartments and the monitoring of biological events in vivo. An ...

Reconstruction From Multiple Poses in Fluorescence Imaging: Proof of Concept

Michaël Unser, Paul Guichard, Denis Fortun, Ning Chu

One disadvantage of all fluorescence imaging modalities is a poor axial resolution. To overcome this issue, we propose a novel approach to reconstruct fluorescence volumes with isotropic high resolution, from images of particle replicates observed at multi ...

Pixel parallel localized driver design for a 128 x 256 pixel array 3D 1Gfps image sensor

Edoardo Charbon, Takeharu Etoh

In this paper, a 3D 1Gfps BSI image sensor is proposed, where 128 × 256 pixels are located in the top-tier chip and a 32 × 32 localized driver array in the bottom-tier chip. Pixels are designed with Multiple Collection Gates (MCG), which collects photons s ...

Intracellular photoactivation and quantification using fluorescence microscopy: chemical tools and imaging approaches

Pablo Rivera Fuentes

Recent advances in optical microscopy enable the visualization and quantification of biol. processes within live cells. To a great extent, these imaging techniques remain limited by the phys. properties of the chem. probes that are used as fluorescent tags ...
