A ratiometric nanoprobe based on carboxylated graphitic carbon nitride nanosheets and Eu 3+ for the detection of tetracyclines

) increases linearly in the 10 nM to 40 μM TC concentration range with a detection limit of 7.7 nM (S/N = 3). It has been successfully applied in the detection of TCs in spiked tap water and soil samples with satisfactory recovery (96.6-107.2%) and high precision. Furthermore, a test paper and smart...
