摘要： Norfloxacin is widely used owing to its strong bactericidal effect on Gram-negative bacteria. However, the residual norfloxacin in the environment can be biomagnified via food chain and may damage the human liver and delay the bone development of minors. Present work described a reliable and sensitive smartphone colorimetric sensing system based on cobalt-doped Fe 3 O 4 magnetic nanoparticles (Co-Fe 3 O 4 MNPs) for the visual detection of norfloxacin. Compared with Fe 3 O 4 , Co-Fe 3 O 4 MNPs earned more remarkably peroxidase-like activity and TMB (colorless) was rapidly oxidized to oxTMB (blue) with the presence of H 2 O 2 . Interestingly, the addition of low concentrati...
