Self-supervised Dense Representation Learning for Live-Cell Microscopy with Time Arrow Prediction

Max Stieber, Martin Weigert, Benjamin Tobias Gallusser

State-of-the-art object detection and segmentation methods for microscopy images rely on supervised machine learning, which requires laborious manual annotation of training data. Here we present a self-supervised method based on time arrow prediction pre-t ...

Event-driven acquisition for content-enriched microscopy

Suliana Manley, Dora Mahecic, Juliette Griffie, Chen Zhang, Martin Weigert, 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 ...

Fluorescent D-Amino Acids for Super-resolution Microscopy of the Bacterial Cell Wall

Luc Reymond, Suliana Manley, Ophélie Rutschmann, Juliette Griffie, Chen Zhang, Willi Leopold Stepp, Jiangtao Qiao, Faustine Ambroisine Charline Ryckebusch

Fluorescent D-amino acids (FDAAs) have previ-ously been developed to enable in situ highlighting of locations of bacterial cell wall growth. Most bacterial cells lie at the edge of the diffraction limit of visible light; thus, resolving the precise details ...

Long-Term, Single-Molecule Imaging of Proteins in Live Cells with Photoregulated Fluxional Fluorophores

Pablo Rivera Fuentes, Annabell Martin, Adam Miklos Eördögh

Single-molecule localization microscopy (SMLM) can reveal nanometric details of biological samples, but its high phototoxicity hampers long-term imaging in live specimens. A significant part of this phototoxicity stems from repeated irradiations that are n ...
