“…In food science, antibiotics abuse has become a focus of people's attention and various COFs-based electrochemical biosensors have been employed to detect antibiotics residues such as ENR, [299] CFX, [89,236] sulfadiazine (SDZ), [177] SMR [179] ], CGA, [100] AMP [88,9] ], kanamycin (Kana), [238] TOB, [120,230] CAP, [192,235] OTC, [87] TC, [131] furazolidone (FA) [74] and so on in meat, fruit, vegetable and beverage. In addition, pesticide residues, [277,301] toxin, [162,241] hormone, [115] environmental hormones, [302] and other biological small molecules such as DA [186] and AA [217] in food samples also have been detected using COFs-based electrochemical sensing methods. Because of excellent natures of COFs, these biosensors all showed good analytical performances including high sensitivity, good selectivity, wide linear ranges, good reproducibility and high stability, implying great application potential (Table 2).…”
