However, polarization is often ignored, in particular for bio-imaging applications. We develop methodologies for optical microscopy that exploit the polarization of light by controling the incident or detected polarization states. These approaches allow retrieving molecular orientational information in biological media, from complex bio-molecular assemblies down to single molecules. The methodology is also applied for the study of nanostructures, either dielectric or metallic.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-5221\" src=\"https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar1-mosaic.jpg\" alt=\"\" width=\"1384\" height=\"925\" srcset=\"https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar1-mosaic.jpg 1384w, https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar1-mosaic-300x201.jpg 300w, https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar1-mosaic-1024x684.jpg 1024w, https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar1-mosaic-768x513.jpg 768w, https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar1-mosaic-160x107.jpg 160w, https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar1-mosaic-195x130.jpg 195w\" sizes=\"auto, (max-width: 1384px) 100vw, 1384px\" \/><\/p>\n<p><strong>Excitation fluorescence approaches<\/strong><\/p>\n<p>Although these techniques are not compatible with single molecule measurements, they are the most commonly used for bio-molecular assemblies. These techniques exploit the fact that fluorescence is maximized when the polarization state of the excitation laser matches the orientation of molecules. For each pixel of an image, we probe the 2D orientation (projection onto the sample plane) and degree of organization of fluorophores attached to proteins of interest. This approach has been successfully applied to studying the organization of cell membrane lipids and actin filaments, and it can be extended to examine orientational changes in membrane proteins, for example. Additionally, probing molecular organization has great potential for visualizing cytoskeletal filament reorganization, such as during morphogenetic events, in real time at the molecular scale. This can help elucidate how these structures contribute to the mechanical properties of cells and tissues, and reveal the roles of associated regulatory proteins. \u00a0A major part of this work is currently carried out in collaboration with Manos Mavrakis (MOSAIC team), who studies cytoskeletal proteins such as actin and septin. Lastly, the freely shareable (open source) data analysis software, PyPOLAR, has been co-developed with the Mathematics Institute of Marseille (I2M).<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-5222\" src=\"https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar2-mosaic.jpg\" alt=\"\" width=\"1384\" height=\"965\" srcset=\"https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar2-mosaic.jpg 1384w, https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar2-mosaic-300x209.jpg 300w, https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar2-mosaic-1024x714.jpg 1024w, https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar2-mosaic-768x535.jpg 768w, https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar2-mosaic-160x112.jpg 160w, https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar2-mosaic-186x130.jpg 186w\" sizes=\"auto, (max-width: 1384px) 100vw, 1384px\" \/><\/p>\n<p><strong>Detection fluorescence approaches<\/strong><\/p>\n<p>These approaches exploit the distinct fluorescence emission, both in intensity and polarization, that depends on the orientation of each emitter. These approaches can be used with single molecule measurements, meaning that (1) they are compatible with super-resolution imaging (~10 nm by e.g. STORM, PALM, PAINT), and \u00a0that (2) they can offer information on the mean orientation and wobbling (orientational flexiblitiy) of the single emitters. Note that these techniques can offer easily 3D orientation information compared to the excitation approaches. We have shown the possiblility of reconstructing super-resolution orientation images using their localization information, while the orientational flexibility is an important parameter to quantify that we are able to retrieve realistic structural information on the labeled bio-molecules. This approach has been applied to organized filaments such as dsDNA, actin stress fibers, microtubules. Currently developed and exploited techniques are PSF engineering techniques, such as CHIDO and C3POL, and ratiometric techniques either based on polarization splitting, such as 4Polar and 4Polar 3D, or BFP splitting.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-5223\" src=\"https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar3-mosaic.jpg\" alt=\"\" width=\"1347\" height=\"916\" srcset=\"https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar3-mosaic.jpg 1347w, https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar3-mosaic-300x204.jpg 300w, https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar3-mosaic-1024x696.jpg 1024w, https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar3-mosaic-768x522.jpg 768w, https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar3-mosaic-160x109.jpg 160w, https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar3-mosaic-191x130.jpg 191w\" sizes=\"auto, (max-width: 1347px) 100vw, 1347px\" \/><\/p>\n<p><strong>Polarized non-linear imaging<\/strong><\/p>\n<p>Due to the nonlinear vectorial coupling between incident light polarizations and molecular bonds \/ molecular induced dipoles directions, tunable incident polarizations lead to a modulation of nonlinear label-free signals (Second Harmonic Generation\u00a0: SHG, Coherent Anti Stokes Raman Scattering\u00a0: CARS, Stimulated Raman Scattering\u00a0: SRS) that can be directly related to the orientational order of biological molecules, without the need of a fluorescent label. We have applied polarized nonlinear microscopy to quantitatively retrieve organizational order in collagen in tissues (by polarized SHG) and lipid structures (by polarized CARS). This methodology is highly sensitive to lipid phases but also to sub-diffraction scale morphological changes in cell membranes. Polarization resolved CARS (pCARS) is now used to image the effect of neurodegenerative diseases on fine myelin structure changes, in mice spinal cord tissues. We are currently developing schemes that allow polarized nonlinear imaging to reach fast imaging rates, either by fast polarization tuning, or via the use of projection on circular polarization combinations. We are also studying the possibilities to develop optical schemes capable to measure the orientation of molecular distributions in 3D, an information which is important in complex tissues. All together these approaches should permit to better quantify molecular order in live and in 3D in tissues related to the study of diseases such as neurodegenerative diseases or cancer.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-5224\" src=\"https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar4-mosaic.png\" alt=\"\" width=\"943\" height=\"347\" srcset=\"https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar4-mosaic.png 943w, https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar4-mosaic-300x110.png 300w, https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar4-mosaic-768x283.png 768w, https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar4-mosaic-160x59.png 160w, https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar4-mosaic-353x130.png 353w\" sizes=\"auto, (max-width: 943px) 100vw, 943px\" \/><\/p>\n<p><strong>Theoretical optics of polarization<\/strong><\/p>\n<p>A good theoretical understanding of polarization in the paraxial and nonparaxial regimes is essential for the appropriate estimation and characterization of molecule orientation and wobbling, their effect on the captured images, and the optimization of the imaging systems used to measure them. We study different theoretical formalisms for characterizing the polarization of nonparaxial electromagnetic fields, for which the field oscillations are not constrained to a plane normal to the direction of propagation. We seek for geometric descriptions of these oscillations, valid in different regimes, on the one hand to understand the inherent dimensionality, geometry and topology of these spaces, while on the other to optimize their characterization. We also explore different aspects of nonparaxial polarization of interest beyond fluorescence microscopy, such as the presence of transverse or longitudinal spin, interpretations for geometric phases, or types of electromagnetic field that are analogues of skyrmions.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-5225\" src=\"https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar5-mosaic.jpg\" alt=\"\" width=\"1375\" height=\"867\" srcset=\"https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar5-mosaic.jpg 1375w, https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar5-mosaic-300x189.jpg 300w, https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar5-mosaic-1024x646.jpg 1024w, https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar5-mosaic-768x484.jpg 768w, https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar5-mosaic-160x101.jpg 160w, https:\/\/www.fresnel.fr\/wp\/wp-content\/uploads\/2026\/01\/polar5-mosaic-206x130.jpg 206w\" sizes=\"auto, (max-width: 1375px) 100vw, 1375px\" \/><\/p>\n<p><strong><span style=\"font-size: 18pt;\">Developped polarized microscopy techniques<\/span><\/strong><br \/>\n<strong>Fluorescence and nonlinear imaging based on excitation schemes:<\/strong><br \/>\n\u2013 Spinning disk fluorescence microscopy (live polarization imaging)<br \/>\n\u2013 Nonlinear scanning polarized microscopy (2-photon fluorescence, SHG, CARS, SRS)<\/p>\n<p><strong>Super-resolution and single molecule microscopy based on detection schemes :<\/strong><br \/>\n\u2013 2D Polarized STORM microscopy<br \/>\n\u2013 3D polarized STORM microscopy (using polarization splitting, BFP splitting or PSF engineering)<\/p>\n<p>&nbsp;<\/p>\n<p><strong><span style=\"font-size: 18pt;\">Publications<\/span><\/strong><\/p>\n<p><strong>2025<\/strong><\/p>\n<p>Brasselet S, Lew MD. , <em>Single molecule orientation and localization microscopy,<\/em>\u00a0<strong>Nat Photonics<\/strong>. 2025 Sep;19:925-937. doi: <a href=\"https:\/\/www.nature.com\/articles\/s41566-025-01724-y\" target=\"_blank\" rel=\"noopener\">10.1038\/s41566-025-01724-y<\/a><\/p>\n<p>Martins CS, Iv F, Suman SK, Panagiotou TC, Sidor C, Ruso-L\u00f3pez M, Plancke CN, Omi S, Pag\u00e8s R, Gomes M, Llewellyn A, Bandi SR, Ramond L, Arbizzani F, Rimoli CV, Schnorrer F, Robin F, Wilde A, LeGoff L, Pedelacq JD, J\u00e9gou A, Cabantous S, Rincon SA, Chandre C, Brasselet S, Mavrakis M. <em>Genetically encoded reporters of actin filament organization in living cells and tissue<\/em>s. <strong>Cell<\/strong>. 2025 May 1;188(9):2540-2559.e27. doi:<a href=\"https:\/\/doi.org\/10.1016\/j.cell.2025.03.003\" target=\"_blank\" rel=\"noopener\" name=\"SMASHVisited\">10.1016\/j.cell.2025.03.003<\/a><\/p>\n<p><strong>2024<\/strong><\/p>\n<p>Herrera I, Alem\u00e1n-Casta\u00f1eda LA, Brasselet S, Alonso MA. <em>Stokes-based analysis for the estimation of 3D dipolar emission<\/em>. <strong>J Opt Soc Am A Opt Image Sci Vis<\/strong>. 2024 Nov 1;41(11):2134-2148. doi:<a href=\"http:\/\/10.1364\/JOSAA.538706\" target=\"_blank\" rel=\"noopener\">10.1364\/JOSAA.538706<\/a><\/p>\n<p>R.
