High-resolution Optical Imaging for Biology

The central aim of the Danzl lab, starting in early 2017, will be to shed light on problems of biological and ultimately also medical relevance using a set of advanced light microscopy tools.

In terms of microscopy, the emphasis will be on approaches that are not limited in their spatial resolving power by the diffraction of light waves. This diffraction resolution limit entails a maximally achievable resolution of ~200 nm for conventional light microscopy. Diffraction-unlimited methods with a resolution of tens of nanometres allow capturing more details of biological specimens than conventional light microscopy approaches.

Analysing living cells and tissues at high spatial and temporal resolution in a minimally perturbative way poses a significant challenge. To this aim, we will engage in the development of novel imaging approaches, building on our expertise both in fundamental physics and in high-resolution imaging, and we will integrate the imaging with the latest technologies to manipulate cells and tissues and to label them for imaging.

The biologists in our interdisciplinary group will thus be able to directly employ highest performance optical microscopes tailor-made for addressing a specific biological problem while the physicists/engineers in the group will enjoy their developments being driven by biological problems and finding immediate application.
