Description
Li Li, Ming Zhang, Xiang Liu, and Shaoqing Zhu build a glow sensor that switches off and on to catch iron and vitamin C in two thousand twenty-four. Vitamin C guards food as an antioxidant, but too much harms health, so both it and iron ions need cheap tracking.
Their carbon dots, doped with nitrogen and phosphorus, are cooked in one hot-water step from sugar and a phosphate salt. The dots shine brightly and hold steady in water and light. Iron ions dim the glow; vitamin C then revives it by converting the iron. Detection limits run extremely low for both. Trials on tap water and canned fruit soup gave sound results, backing field use.
