EMBL Course: Time-Resolved STED Nanoscopy for Life Sciences

Jointly organized by Leica Microsystems and EMBL, this year another course on time-resolved STED (stimulated emission depletion) nanoscopy and its use for life science applications will take place 13 to 18 July at the EMBL Imaging Center.

The course is intended for researchers who are in the early stages of their career in the life sciences, e.g., pre- or post-doctoral level, and ideally have access to a STED microscope. The entire range of skills needed to take advantage of STED nanoscopy for life science applications will be covered.

Topics covered

The following topics will be addressed during lectures, tutorials, and practical workshops:

  • Sample preparation for STED microscopy, including choice of fluorophores and refractive index matching
  • Technical implementations: pulsed-STED, gated-STED, and time-resolved STED (tauSTED)
  • Multi-color 2D and 3D STED microscopy
  • Image acquisition strategies for live-cell STED
  • STED multiplexing via lifetime-based fluorophore separation
  • Clearing for large volume STED imaging and adaptive motCORR (motorized correction) objectives
  • Expansion-microscopy STED
  • Deconvolution of time-resolved STED data
  • Image analysis

Intended outcomes 

At the end of the course, the participants will be able to design experiments using STED microscopy, prepare high-quality microscopy samples, and acquire state-of-the-art nanoscopy images.

Date: 13 - 18 July, 2026
Location: on site at the EMBL Imaging Center
Hosted by: Leica Microsystems and EMBL

What past participants say about the course:

The EMBL super-resolution microscopy course was exactly tailored to my needs and will allow me to get my own experiments running independently. Also, contacts I made will be very useful in the future!” – Paul Markus Müller, Freie Universität Berlin, Germany

Very well organized and conceived course. Everything is covered here including the fundamentals, the practical sessions, creative application, innovative development of STED technology. If you are interested in nanoscopy, I would recommend you participate in this course.”  – Shao-Chun ‘Peggy’ Hsu, National Taiwan University, Taiwan
