Event-driven acquisition for content-enriched microscopy

Suliana Manley, Dora Mahecic, Willi Leopold Stepp, Chen Zhang, Martin Weigert, Juliette Griffie

Event-driven acquisition uses neural-network-based recognition of specific biological events to trigger switching between slow and fast super-resolution imaging, enriching the capture of interesting events with high spatiotemporal resolution. A common goal ...

Flipper Probes for the Community

Suliana Manley, Dora Mahecic

This article describes four fluorescent membrane tension probes that have been designed, synthesized, evaluated, commercialized and applied to current biology challenges in the context of the NCCR Chemical Biology. Their names are Flipper-TR (R), ER Flippe ...

Mitochondrial membrane tension governs fission

Suliana Manley, Lina Carlini, Dora Mahecic, Tatjana Isabelle Kleele

During mitochondrial fission, key molecular and cellular factors assemble on the outer mitochondrial membrane, where they coordinate to generate constriction. Constriction sites can eventually divide or reverse upon disassembly of the machinery. However, a ...

Experimental Combination of Super-Resolution Optical Fluctuation Imaging with Structured Illumination Microscopy for Large Fields-of-View

Aleksandra Radenovic, Suliana Manley, Vytautas Navikas, Adrien Charles-François Raymond Descloux, Kristin Stefanie Grussmayer, Dora Mahecic

All fluorescence super-resolution microscopy techniques present trade-offs between, for example, resolution, acquisition speed, and live-cell compatibility. Structured illumination microscopy (SIM) improves the resolution through successive imaging of the ...

Distinct fission signatures predict mitochondrial degradation or biogenesis

Suliana Manley, Hélène Danielle Perreten Lambert, Julius Hans Bernd Winter, Dora Mahecic, Timo Henry René Rey, Tatjana Isabelle Kleele

Mitochondrial fission is a highly regulated process that, when disrupted, can alter metabolism, proliferation and apoptosis(1-3). Dysregulation has been linked to neurodegeneration(3,4), cardiovascular disease(3) and cancer(5). Key components of the fissio ...

Characterization of flat-fielding systems for quantitative microscopy

Suliana Manley, Dora Mahecic, Khalid Ashraf Mohie Ibrahim

Optical flat-fielding systems, such as field-mapping or integration-based beam shapers, are used to transform nonuniform illumination into uniform illumination. Thus, flat-fielding paves the way for imaging that is independent of position within a field of ...

Homogeneous multifocal excitation for high-throughput super-resolution imaging

Pierre Gönczy, Suliana Manley, Kyle Michael Douglass, Khalid Ashraf Mohie Ibrahim, Davide Gambarotto, Paul Guichard, Virginie Hamel, Niccolo Banterle, Dora Mahecic, Denis Fortun

Super-resolution microscopies have become an established tool in biological research. However, imaging throughput remains a main bottleneck in acquiring large datasets required for quantitative biology. Here we describe multifocal flat illumination for fie ...

Koehler integrator device and application thereof in a multi-focal confocal microscope

Suliana Manley, Kyle Michael Douglass, Dora Mahecic

A Koehler integrator device (10) comprises a collimating lens (11) being arranged for collimating a light field created by an incoherent or partially coherent light source, a pair of planar first and second micro-lens arrays (12, 13) being arranged for rel ...

High-throughput and adaptive super-resolution fluorescence microscopy of organelles

Dora Mahecic

Fluorescence super-resolution microscopy has allowed unprecedented insight into the workings of biological systems below the diffraction limit of light. Over the past decade, it has overcome several challenges to deliver 3D, multi-color and faster imaging ...
