Light switch for life: Controlling molecular droplets with UV

Biomolecular condensates are tiny, droplet-like structures made up of molecules that help organize key processes in living organisms. Because they are so small and constantly changing, it has been difficult for scientists to measure their physical properties or control how they behave. Leiden researchers at the Mashaghi Lab have now discovered a surprising new way to shape and control tiny droplets of molecules found in living organisms. The breakthrough could lead to smarter biomaterials, improve drug delivery and even new insights into the emergence of life on Earth. The work is published in Nature Communications.
