Developing international talent “Studienwege International – Göttingen MINT Journey for Internationals” means our Uni can recruit students to degree programmes in Chemistry and Physics (taught in German) and support them in a specially tailored Semester Zero: www.uni-goettingen.de/en/3240.html...

Our group was awarded a RiseUp! grant of the Böhringer Ingelheim Foundation 🙏🎉 We're thus looking for 2 Doctoral Researchers to find with us new ways to light-regulate enzyme function: www.uni-goettingen.de/de/644546.ht... Special thanks to the team for building the foundation of the project💡🙏

🚀 Just published! In PhD work by first author Dongchen Du, we’ve developed a simple, byproduct-free labeling strategy using imidazopyridinium dyes formed in situ from isoquinolines! onlinelibrary.wiley.com/doi/full/10.... #Fluorescence #Bioconjugation #ChemicalBiology #InSituLabeling

In Situ Construction of Imidazopyridinium Fluorescent Labels for Bioconjugation

Chromophore engineering of isoquinoline aldehydes generates TICT-based fluorogenic dyes for in situ labeling of diverse (bio)molecules with large Stokes shifts compatible with cell imaging.
