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. 🤩

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.

Ever wondered how to perform tens of thousands of nanoliter droplet manipulations in a truly parallel fashion? Here we show a method that enables parallel medium exchange in thousands of nanoliter-scale cell cultures, facilitates the extraction of nanoliter-sized aliquots from thousands of nanodroplets, and allows for the simultaneous transfer of single-cell spheroids between individual 200 nL droplets—in seconds and across thousands of droplets at once! 💪
