Coacervates offer dynamic environments for molecular organization. Using complex coacervates of poly-L-lysine and anionic fluorophores, we show that the coacervate microenvironment modulates dye photophysical properties through competing effects: fluorescence enhancement via local enrichment and aggregation-induced quenching at higher loading, while enabling energy transfer. These insights establish coacervates as versatile templates for designing adaptive nanoscale photonic and energy-transfer materials.

Protein Dynamics in Living Cells
Fluorescent recovery after photobleaching (FRAP) is a fluorescent-protein-based detection technique used to quantify protein movement rates within the cell. This method exposes a small portion of the cell to an intense laser beam. The laser beam causes permanent photobleaching of the fluorophore-tagged proteins in the exposed region. As the bleached...
