Exploring Neural Cell Dynamics with Digital Holographic Microscopy

Pierre Magistretti, Christian Depeursinge, Pierre Marquet

In this review, we summarize how the new concept of digital optics applied to the field of holographic microscopy has allowed the development of a reliable and flexible digital holographic quantitative phase microscopy (DH-QPM) technique at the nanoscale p ...

Automated statistical quantification of three-dimensional morphology and mean corpuscular hemoglobin of multiple red blood cells

Pierre Marquet, Daniel Boss

In this paper, we present an automated approach to quantify information about three-dimensional (3D) morphology, hemoglobin content and density of mature red blood cells (RBCs) using off-axis digital holographic microscopy (DHM) and statistical algorithms. ...

Spatially-Resolved Eigenmode Decomposition of Red Blood Cells Membrane Fluctuations Questions the Role of ATP in Flickering

Pierre Magistretti, Dimitri Nestor Alice Van De Ville, Christian Depeursinge, Benjamin Rappaz, Pierre Marquet, Daniel Boss, Annick Hoffmann

Red blood cells (RBCs) present unique reversible shape deformability, essential for both function and survival, resulting notably in cell membrane fluctuations (CMF). These CMF have been subject of many studies in order to obtain a better understanding of ...

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 ...

High b-value diffusion-weighted imaging: a sensitive method to reveal white matter differences in schizophrenia

Jean-Philippe Thiran, Reto Meuli, Pierre Marquet, Patric Hagmann, Djalel Eddine Meskaldji, Philipp Baumann, Leila Cammoun

Over the last ten years, Diffusion-weighted Imaging (DWI) has become an important tool to investigate white matter (WM) anomalies in schizophrenia. Despite technological improvement and the exponential use of this technique, discrepancies remain and little ...

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 ...

Recognition and classification of red blood cells using digital holographic microscopy and data clustering with discriminant analysis

Pierre Marquet, Daniel Boss

We propose to apply statistical clustering algorithms on a three-dimensional profile of red blood cells (RBCs) obtained through digital holographic microscopy (DHM). We show that two classes of RBCs stored for 14 and 38 days can be effectively classified. ...

Quantitative phase restoration by direct inversion using the optical transfer function

Christian Depeursinge, Pierre Marquet, Shanshan Kou, Laura Waller

Quantitative phase recovery of phase objects is achieved by a direct inversion using the defocused weak object transfer function. The presented method is noniterative and is based on partially coherent principles. It also takes into account the optical pro ...
