Superresolution Microscopy

In order to investigate biological questions that were previously inaccessible because of the limited resolution of light microscopes, we are developing novel superresolution microscopy tools. The design and implementation of advanced microscopes is crucially based on physics and engineering such as optics, mechanical and electrical engineering, image analysis and software development.

Currently we are developing the following tools:

  1. Automated localization microscope for high-throughput superresolution imaging of entire proteomes.
  2. Robust three-dimensional superresolution microscopy with isotropic resolution.
  3. Superresolution microscopy with single-plane illumination.
  4. Microfluidics for superresolution microscopy.
