A Single Sub-Millimetric Metasurface-Based Optical Element for Lattice Bessel Beam Excitation Enabling Brain Activity Recordings In Vivo

Bessel beams (BBs) are propagation-invariant optical fields that retain a narrow central intensity profile over longer propagation lengths than Gaussian beams (GBs). Due to this property, they have been adopted in fluorescence-based light sheet microscopy ...

Waveguide platform and methods for super-resolution fluorescence microscopy of sub-cellular structures

Anna Archetti

Super-resolution fluorescence microscopy is widespread, owing to its demonstrated ability to resolve dynamical processes within cells and to identify the structure and position of specific proteins in the interior of protein complexes. Nowadays, subcellula ...

Multi-phosphorylation reaction and clustering tune Pom1 gradient mid-cell levels according to cell size

Suliana Manley, Anna Archetti, Lina Carlini, Charlotte Sophia Floderer, Thaïs Reichler

Protein concentration gradients pattern developing organisms and single cells. In Schizosaccharomyces pombe rod-shaped cells, Pom1 kinase forms gradients with maxima at cell poles. Pom1 controls the timing of mitotic entry by inhibiting Cdr2, which forms s ...

Waveguide-PAINT offers an open platform for large field-of-view super-resolution imaging

Aleksandra Radenovic, Suliana Manley, Evgenii Glushkov, Anna Archetti, Anton Stroganov

Super-resolution microscopies based on the localization of single molecules have been widely adopted due to their demonstrated performance and their accessibility resulting from open software and simple hardware. The PAINT method for localization microscop ...

Constriction Rate Modulation Can Drive Cell Size Control and Homeostasis in C. crescentus

Suliana Manley, Seamus John Holden, Anna Archetti, Aster Louis K Vanhecke, Ambroise Justin Lambert, Felix Max Schaber

Rod-shaped bacteria typically grow first via sporadic and dispersed elongation along their lateral walls and then via a combination of zonal elongation and constriction at the division site to form the poles of daughter cells. Although constriction compris ...

Super-resolution imaging of multiple cells by optimized flat-field epi-illumination

Suliana Manley, Kyle Michael Douglass, Christian Sieben, Anna Archetti, Ambroise Justin Lambert

Biological processes are inherently multi-scale, and supramolecular complexes at the nanoscale determine changes at the cellular scale and beyond. Single-molecule localizationmicroscopy (SMLM)(1-3) techniques have been established as important tools for st ...
