Carbon dots-based fluorescence spectrometry for pesticides sensing

Deltamethrin and fenvalerate in vegetables and rice

“…These efforts would enable the establishment of diverse and robust optical sensing systems for target analytes. 29,30 In this study, green-uorescent carbon dots were fabricated from Moringa oleifera (as the precursor) (MO-CDs) using phosphoric acid (H 3 PO 4 ) as a doping agent and were then used as a probe for sensing DLM and FV in food samples. The acidic conditions obtained due to H 3 PO 4 led to a dehydration reaction of the MO, which is a fast-growing, drought-resistant tree that is native to the Indian subcontinent, promoting the carbonization of the phytochemicals (avonoids, phenolic acid, alkaloids, steroids, saponins, glucosinolate, and terpenes) in the MO and resulting in the formation of CDs.…”
