Magnetic Fe–N–C nanoparticles as a dual nanozyme for label-free colorimetric detection of antibiotics

Abstract

In this study, we reported a simple one-step pyrolytic strategy for fabrication of N-C codoped Fe-based nanoparticles (Fe-N-C) and exhibited their oxidase-mimic and peroxidase-mimic activity in a chromogenic reaction with...

Nanozymes: powerful catalytic materials for environmental pollutant detection and degradation

“…With this principle, several studies have been reported to develop nanozyme catalysis-based assays of antibiotics. 137–140,150 Che et al synthesized three shapes of g-C 3 N 4 with different peroxidase and fluorescence properties via adjusting the degrees of planar connectivity and interlayer stacking. 150 To improve enzymatic activity and amplify the difference in signals toward different antibiotics, in situ growth of an equivalent amount of MIL-101(Fe) on the three morphologies of g-C 3 N 4 was performed.…”
