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

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 ...

Distinct fission signatures predict mitochondrial degradation or biogenesis

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

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 ...

Strategies for increasing the throughput of super-resolution microscopies

Suliana Manley, Dora Mahecic, Juliette Griffie

Fluorescence microscopy methods have been developed to circumvent the diffraction limit by exploiting nonlinearities in the interactions between light and fluorophores. Initially, these methods were up to orders of magnitude slower than standard microscopi ...

Event-driven acquisition for content-enriched microscopy

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

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 ...

Mechanosensitive Fluorescent Probes to Image Membrane Tension in Mitochondria, Endoplasmic Reticulum, and Lysosomes

Suliana Manley, Dora Mahecic

Measuring forces inside cells is particularly challenging. With the development of quantitative microscopy, fluorophores which allow the measurement of forces became highly desirable. We have previously introduced a mechanosensitive flipper probe, which re ...

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

Suliana Manley, Dora Mahecic, Kyle Michael Douglass

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 ...

Homogeneous multifocal excitation for high-throughput super-resolution imaging

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

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 ...

Mitochondrial membrane tension governs fission

Suliana Manley, Dora Mahecic, Lina Carlini, 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, Dora Mahecic, Kristin Stefanie Grussmayer

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 ...
