Colloidal gold immunochromatography has the characteristics of high specificity,high sensitivity,and high repeatability,which can accurately detect the targeted analytes in the samples,and has a wide range of applications in the field of rapid detection.This study used colloidal gold immunochromatography to rapidly detect norfloxacin(NOR)residues in animal-derived foods(pork,chicken,fish,shrimp,and eggs)and validated the method with a relative accuracy of 97.0％.The limit of detection was down to 2 μg/kg,showing high detectability.By testing the above-mentioned five different matrix samples,the NOR colloidal gold rapid detection method attained a sensitivity of 99％,specificity of 98％,false positive rate of 2％,and false negative rate of 1％.This method proved simple,rapid,sensitive,and accurate,and thereby was practically applicable for the rapid,precise detection of NOR in complicated matrices.
