A Bifunctional CoFcMOF Nanozyme Enables Dual-Mode PEC-Colorimetric Immunosensing of C-Reactive Protein with Built-In Cross-Validation.

C-reactive protein (CRP), a key inflammatory biomarker, plays a critical role in clinical diagnostics; however, its reliable quantification demands analytical methods that surpass the limitations of conventional single-mode detection by integrating high sensitivity with built-in signal fidelity. Herein, we report a dua...

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...
