Combined Optical Coherence and Fluorescence Microscopy to assess dynamics and specificity of pancreatic beta-cell tracers

Theo Lasser, Anne Grapin-Botton, Arno Pino Bouwens, Christophe Pache, Daniel Pawel Szlag, Corinne Berclaz, Antonio Lopez

The identification of a beta-cell tracer is a major quest in diabetes research. However, since MRI, PET and SPECT cannot resolve individual islets, optical techniques are required to assess the specificity of these tracers. We propose to combine Optical Co ...

Optical coherence correlation spectroscopy (OCCS)

Theo Lasser, Marcel Leutenegger, Christophe Pache, Arno Pino Bouwens, Stefan Geissbühler, Akihiro Sato, Stéphane Broillet

We present a new method called optical coherence correlation spectroscopy (OCCS) using nanoparticles as reporters of kinetic processes at the single particle level. OCCS is a spectral interferometry based method, thus giving simultaneous access to several ...

Visible light optical coherence correlation spectroscopy

Theo Lasser, Heinrich Hofmann, Marcel Leutenegger, Arno Pino Bouwens, Lionel André Maurizi, Daniel Pawel Szlag, Stéphane Broillet

Optical coherence correlation spectroscopy (OCCS) allows studying kinetic processes at the single particle level using the backscattered light of nanoparticles. We extend the possibilities of this technique by increasing its signal-to-noise ratio by a fact ...

Quantitative cerebral blood flow imaging with extended-focus optical coherence microscopy

Theo Lasser, Arno Pino Bouwens, Tristan Bolmont, Daniel Pawel Szlag, Corinne Berclaz

Quantitative three-dimensional blood flow imaging is a valuable technique to investigate the physiology of the brain. Two-photon microscopy (2PM) allows quantification of the local blood flow velocity with micrometric resolution by performing repeated line ...

Functional and Structural Imaging with Optical Coherence Microscopy : Principles & Applications

Arno Pino Bouwens

Fluorescence microscopy techniques are well established research tools and have proven their use in a large variety of biomedical applications. Microscopic molecular contrast is achieved by imaging fluorescent dyes that bind specifically to a molecule of i ...

Quantitative lateral and axial flow imaging with optical coherence microscopy and tomography

Theo Lasser, Arno Pino Bouwens, Tristan Bolmont, Daniel Pawel Szlag

Optical coherence tomography (OCT) and optical coherence microscopy (OCM) allow the acquisition of quantitative three-dimensional axial flow by estimating the Doppler shift caused by moving scatterers. Measuring the velocity of red blood cells is currently ...

Diabetes imaging — quantitative assessment of islets of Langerhans distribution in murine pancreas using extended-focus optical coherence microscopy

Dimitri Nestor Alice Van De Ville, Theo Lasser, Anthony Christopher Davison, Anne Grapin-Botton, Martin Villiger, Arno Pino Bouwens, Corinne Berclaz, Joan Goulley, Erica Martin-Williams

Diabetes is characterized by hyperglycemia that can result from the loss of pancreatic insulin secreting β-cells in the islets of Langerhans. We analyzed ex vivo the entire gastric and duodenal lobes of a murine pancreas using extended-focus Optical Cohere ...

Fast three-dimensional imaging of gold nanoparticles in living cells with photothermal optical lock-in Optical Coherence Microscopy

Theo Lasser, Christian Santschi, Martin Villiger, Christophe Pache, Arno Pino Bouwens, Corinne Berclaz, Noelia Laura Bocchio, Matthew Gibson, Joan Goulley

We introduce photothermal optical lock-in Optical Coherence Microscopy (poli-OCM), a volumetric imaging technique, which combines the depth sectioning of OCM with the high sensitivity of photothermal microscopy while maintaining the fast acquisition speed ...

Zero-crossing approach to high-resolution reconstruction in frequency-domain optical-coherence tomography

Theo Lasser, Marcel Leutenegger, Arno Pino Bouwens, Chandra Sekhar Seelamantula

We address the problem of high-resolution reconstruction in frequency-domain optical-coherence tomography (FDOCT). The traditional method employed uses the inverse discrete Fourier transform, which is limited in resolution due to the Heisenberg uncertainty ...
