Our newest publication in Angewandte Chemie! We synthesized 325 analogues of mirdametinib, screened them on HT29 colon cancer cells, and identified 46 hits that showed equal or even higher activity compared to the clinically approved mirdametinib. Huge thanks to all co-authors—special thanks to our first authors Maximilian Seifermann Julius Höpfner, and Liana Bauer—and to our outstanding collaborators Prof. Dr. Carsten Hopf and Stefan Schmidt from the Center for Mass Spectrometry and Optical Spectroscopy (CeMOS) in Mannheim!

This work presents a novel approach for the extraction or addition of substances and purification of chemical synthesis in a miniaturized, high-throughput (HT) manner. It is based on high droplet stability on the Droplet Microarray (DMA), allowing the complete immersion of a miniaturized array with up to 2688 15 nL-droplets into an organic solvent and simultaneous treatment of all droplets. Congratulations to Michelle J. Iwohn and Janne J. Wiedmann!

For several years, our research group has been participating in this exciting event—the Dragon Boat competition on the Neckar River in Heidelberg. It is probably the best team-building activity one can imagine: 19 group members and friends in the same boat, competing against other teams. It was once again an amazing event on the beautiful banks of the Neckar, with Heidelberg Castle on the other side. The times of our three races were 1:21.52, 1:23.77, and 1:15.30 🥳. Thanks to everyone who participated and organized!

Lipid nanoparticles (LNPs) are important for biological research, vaccine development, cell transfection, etc. Unfortunately, in our experience, in vitro transfection does not directly translate to successful in vivo gene delivery. In this Advanced Healthcare Materials paper, which was an amazing collaboration with Merck Life Science, we designed and synthesized several novel unsaturated lipids with novel slightly more hydrophobic head groups and studied their LNPs. Most importantly, through intelligent design of the lipid structures (both headgroup and tail), we were able to develop LNPs without fusogenic activity in blood cells, with the right pKa, and finally with highly efficient mRNA delivery in vivo. I recommend reading this paper for those who work on lipid synthesis, LNPs, and vaccine development. Thanks to Eleni Samaridou, Johanna Simon, Moritz Beck-Broichsitter, Gary Davidson for the great joint project!

Every year, our group escapes the lab for a short retreat — three days of fresh air and deep thoughts. We talk, discuss science, do brainstorming sessions, cook and hike together. This year, we spent our retreat in beautiful Bavaria — and of course, we visited a beer brewery. Always grateful for these moments of science, nature, and fun with an amazing team. 🤩

Our paper on electrode droplet microarrays (eDMA) is now on the cover of Advanced Healthcare Materials. Very nice photograph, so it had to go to the cover;) Thanks to Anna Popova and Heinz-Georg Jahnke for the nice work and congrats to all the authors.

In this paper, we demonstrate the encapsulation of cells or individual cell spheroids within nanoliter-scale hydrogels. This method enables on-demand immobilization of cells or cell spheroids on an array slide, facilitating subsequent culturing, washing, or immersion into media without cell detachment. The selective gelation of individual droplets is particularly interesting, as it allows for sorting cells or single-cell spheroids by stabilizing desired droplets while removing unwanted spheroids from the surface through simple washing. This approach holds potential for high-throughput cell screenings and miniaturized workflows in 3D microenvironments, advancing research in fields such as cell, spheroid or organoid screenings, drug discovery, and precision medicine.

Yesterday, our group visited Wiley in Weinheim, we had a great time talking to the editors and left our mark on their wall at the end! ;)
