Colorimetric-SERS Dual-Mode Detection of Organophosphorus Pesticides Using Au-R-Fe3O4 Nanozyme Cascade Platform: A Practical Approach for Chemistry Education
Organophosphorus pesticides (OPs) pose significant environmental and health risks due to their persistence and neurotoxicity, yet current detection methods rely on sophisticated instrumentation inaccessible to educational settings. To address this pedagogical gap, we developed a recyclable Au-R-Fe3O4 nanozyme cascade...
