An “ON–OFF–ON” Fluorescent Sensor Based on N,S,F‐Doped Carbon Dots for Selective Detection of MnO4− and Dopamine Hydrochloride
Dopamine hydrochloride (DPH) is a key neurotransmitter, and its dysregulated concentration has been linked to various neurological disorders. Meanwhile, potassium permanganate (MnO4−), a potent oxidant, poses significant environmental risks when discharged in excess. Therefore, sensitive detection of MnO4− and DPH is e...
