CeFe nanofibrous carbon nanozyme integrated with smartphone for the point-of-care testing of norfloxacin in water.

ABSTRACT: The overuse of antibiotics has led to the severe contamination of water bodies, posing a considerable hazard to human health. Therefore, the development of an accurate and rapid point-of-care testing (POCT) platform for the quantitative detection of antibiotics is necessary. In this study, Cerium oxide (CeO₂) and Ferrosoferric oxide (Fe₃O₄) nanoparticles were simultaneously encapsulated into N-doped nanofibrous carbon microspheres to form of a novel nanozyme (CeFe-NCMzyme) with a porous structure, high surface area, and N-doped carbon material properties, leading to a considerable enhancement of the peroxidase (POD)-like activity compared with that of the CeO₂ or Fe₃O₄ nanoparticles alone. The POD-like activity of CeFe-NCMzy
