AI Technical Summary
Existing norfloxacin detection methods are costly, have poor operational stability, are sensitive to reaction environments, are difficult to recover and reuse, and are time-consuming and complex, which limits their application in rapid detection.
Dumbbell-shaped iron nanozymes were prepared, and norfloxacin was visualized and detected using an ultraviolet spectrophotometer or RGB extraction detection method with enzyme inhibitors and chromogenic substrates. This simplified the pretreatment steps, reduced costs, and improved sensitivity and accuracy.
It enables rapid, simple, and low-cost quantitative detection of norfloxacin, with a detection range of 0.05-6.00 μmol/L and a detection limit of 27 nmol/L. It has good selectivity and anti-interference ability and is suitable for on-site visual detection.
