A novel molecular imprinting-based turn-on ratiometric fluorescence sensor was constructed via a facile sol–gel polymerization for detection of 2,4-dichlorophenoxyacetic acid (2,4-D) on the basis of photoinduced electron transfer (PET) by using nitrobenzoxadiazole (NBD) as detection signal source an...
