Simultaneous Optical Recording in Multiple Cells by Digital Holographic Microscopy of Chloride Current Associated to Activation of the Ligand-Gated Chloride Channel GABA(A) Receptor

Christian Depeursinge, Benjamin Rappaz, Pierre Marquet, Pascal Jourdain, Daniel Boss, Corinne Moratal

Chloride channels represent a group of targets for major clinical indications. However, molecular screening for chloride channel modulators has proven to be difficult and time-consuming as approaches essentially rely on the use of fluorescent dyes or invas ...

Early Cell Death Detection with Digital Holographic Microscopy

Pierre Magistretti, Christian Depeursinge, Pierre Marquet, Nicolas Pavillon, Pascal Jourdain, Corinne Moratal

Background: Digital holography provides a non-invasive measurement of the quantitative phase shifts induced by cells in culture, which can be related to cell volume changes. It has been shown previously that regulation of cell volume, in particular as it r ...

Determination of Transmembrane Water Fluxes in Neurons Elicited by Glutamate Ionotropic Receptors and by the Co-transporters KCC2 and NKCC1: A Digital Holographic Microscopy Study

Pierre Magistretti, Christian Depeursinge, Benjamin Rappaz, Pierre Marquet, Nicolas Pavillon, Pascal Jourdain, Daniel Boss, Corinne Moratal

Digital holographic microscopy (DHM) is a noninvasive optical imaging technique that provides quantitative phase images of living cells. In a recent study, we showed that the quantitative monitoring of the phase signal by DHM was a simple label-free method ...

Cell Morphology and Intracellular Ionic Homeostasis explored with a Multimodal Approach combining Epifluorescence and Digital Holographic Microscopy

Pierre Magistretti, Christian Depeursinge, Pierre Marquet, Nicolas Pavillon, Jonas Kühn, Pascal Jourdain, Daniel Boss, Aleksandr Benke, Corinne Moratal

The authors have developed a live-cell multimodality microscope combining epifluorescence with digital holographic microscopy; it has been implemented with a decoupling procedure allowing to separately measure from the quantitative phase important cell par ...

Label-free second harmonic phase imaging of biological specimen by digital holographic microscopy

Pierre Magistretti, Christian Depeursinge, Pierre Marquet, Etienne Shaffer, Corinne Moratal

We have previously developed a new way for nonscanning second-harmonic generation (SHG) microscopy [Opt. Lett. 34, 2450 (2009)]. Based on digital holography, this technique captures, in single-shot hologram acquisition, both the amplitude and the phase of ...

Submicrometer tomography of cells by multiple-wavelength digital holographic microscopy in reflection

Christian Depeursinge, Tristan Colomb, Frédéric Montfort, Benjamin Rappaz, Pierre Marquet, Nicolas Pavillon, Jonas Kühn, Corinne Moratal

We present first results on a method enabling mechanical scanning-free tomography with submicrometer axial resolution by multiple-wavelength digital holographic microscopy. By sequentially acquiring reflection holograms and summing 20 wavefronts equally sp ...
