    Gibberellins (GAs) control key growth and developmental processes in plants. Real-time monitoring of GA concentrations in living tissues is critical for understanding the actions of this hormone class. A first-generation optogenetic GA-nano-indicator now illuminates the effects of GA levels on cell length and light signalling.

    Single-molecule detection commonly requires focused laser beams because of the small absorption cross-sections of dye molecules. Now, researchers have shown that thousands of dye molecules in nanoparticles can transfer light excitation to a single acceptor dye, enabling single-molecule detection at sunlight excitation power.
