Zusammenfassung der Projektergebnisse

In conclusion, the research carried out through the Emmy Noether Grant has help tremendously to push DNA-based super-resolution microscopy to the next level, paving the way to quantitative high-throughput studies under biomedically relevant conditions. While we were able to push spatial resolution to below 5 nm as well as improve the labeling probes and image acquisition speed, there is still a dire need in carefully benchmarked, improved labeling probes for next-generation super-resolution microscopy, an area where we actively develop new approaches at the moment. Furthermore, we are pursuing applications of improved DNA-PAINT microscopy to cell-biological and biomedical questions such as the multiplexed visualization of cell surface receptor patterns with single protein resolution.
