Precise measurement of nanoscopic septin ring structures in deep learning-assisted quantitative superresolution microscopy

A. Zehtabian, P. M. Müller, M. Goisser, L. Obendorf, L. Jänisch, N. Hümpfer, J. Rentsch, H. Ewers

The paper uses deep learning and superresolution microscopy to analyze septin ring structures, finding a trade-off between measurement accuracy and dynamic range and showing septin ring size correlates with subunit count.

Expansion stimulated emission depletion microscopy (ExSTED)

M. Gao, R. Maraspini, O. Beutel, A. Zehtabian, B. Eickholt, A. Honigmann, H. Ewers

The paper combines expansion microscopy with STED to achieve 30-fold higher resolution than conventional microscopy, enabling ultra-structural imaging at <10 nm lateral and ~50 nm isotropic.
