Description
Yatao Pan and co-authors build carbon dots that glow in two colors to sense hydroxyl radicals in a 2026 study. Carbon dots are tiny, friendly light emitters used in imaging and sensing. Getting steady dual emission in water has been hard. A one pot heating method uses a sugar as carbon source and an acid to shape surface states.
The dots emit near 450 and 590 nanometers, from core and surface states. Hydroxyl radicals dim only the red band, so the color ratio self corrects and gives very low detection limits with a visible readout. Tests in onion cells under oxidative stress confirmed the sensor can track radical levels in living tissue.
