The Hidden Geometry of Water: Mapping Nanoscale Confinement and Water Properties Inside Peptide–Nucleotide Biomolecular Condensates
Biomolecular condensates formed by liquid–liquid phase separation create dynamic, water-rich microenvironments that are essential for cellular organization, yet it is challenging to understand their internal aqueous phase. Here, we introduce Brønsted photoacids and photobases as a new class of environmental fluorescent...
