Model-Based 2.5-D Deconvolution for Extended Depth of Field in Brightfield Microscopy

Michaël Unser, Dimitri Nestor Alice Van De Ville, François Aguet

Due to the limited depth of field of brightfield microscopes, it is usually impossible to image thick specimens entirely in focus. By optically sectioning the specimen, the in-focus information at the specimen's surface can be acquired over a range of imag ...

Cellular dynamics explored with digital holographic microscopy

Benjamin Rappaz

Obtaining high resolution 3D quantitative images is critical for elucidating the relationship between cell dynamics and physiological or pathological processes. However the feasibility of such cellular dynamic studies is limited by the resolution of the 3D ...

Single molecule imaging of odorant receptors in supported planar lipid membranes

Theo Lasser, Marcel Leutenegger, Iwan Märki

Odorant receptors are an excellent example of natural superiority in binding specific small and hydrophobic molecules. Difficulties in expression, isolation and solubilisation of these receptors have been overcome recently by in vitro synthesis and incorpo ...

Infrared Scanning Near-Field Optical Microscopy Below the Diffraction Limit

Giorgio Margaritondo

Infrared scanning near-field optical microscopy (IR-SNOM) is an extremely powerful analytical instrument since it combines IR spectroscopy's high chemical specificity with SNOM's high spatial resolution. In order to do this in the infrared, specialty chalc ...

Spectral tuning and near-field imaging of photonic crystal microcavities

Romuald Houdré, Laurent Balet, Carl Zinoni, Massimo Gurioli

We experimentally observe a sizable and reversible spectral tuning of the resonances of a two-dimensional photonic crystal microcavity induced by the introduction of a subwavelength size glass tip. The comparison between experimental near-field data, colle ...

Refractive Index Tomography by Digital Holographic Microscopy

Christian Depeursinge, Tristan Colomb, Nicolas Pavillon, Pierre Marquet, Jonas Kühn

3D Refractive Index (RI) tomography appears as a challenging perspective in the observation of microscopic 3D objects, biological cells in particular. Recent developments in Digital Holographic Microscopy have permitted to achieve accurate RI 3D images. ...

Photobleaching-free infrared near-field microscopy localizes molecules in neurons

Giorgio Margaritondo, Kai Johnsson, Harald Hirling, Johanna Generosi, Michel Kropf

High-resolution detection of specific molecules in cells is a major challenge in biology. We show that infrared scanning near-field microscopy can detect the spatial distribution of alpha-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid–type glutamate r ...

Near-field optical images of subwavelength annular aperture arrays exhibiting an extraordinary transmission

Patrik Willi Hoffmann, Christian Santschi

In this paper, we present near-field optical images of nanostructures exhibiting an extraordinary transmission. These structures consist of annular aperture arrays engraved in a metallic film: they are quite promising structures for nanophotonics because o ...
