The design of single-atom catalysts with dual functions has emerged as a promising strategy for developing high-performance sensing platforms. Herein, we reported facile host-guest synthesizing an atomically dispersed Co catalyst (Co-N-C), where atoms were uniformly anchored on the N-doped carbon matrix derived from zeolitic imidazolate framework-8. as-prepared Co-N-C exhibits both excellent electrochemical and peroxidase-like colorimetric activities toward detection three important bioactive small molecules, ascorbic acid (AA), dopamine (DA), uric (UA). sensor demonstrated ultrahigh sensitivity limits 4.83, 1.36, 0.371 μM AA, DA, UA, respectively, along outstanding selectivity against common interferents stable performance. Meanwhile, method also showed analytical performance 2.24 3.09 2.97 results indicate that electronic modulation through precise nitrogen coordination enhances affinity Co-Nx target reactants, thereby promoting adsorption electron transfer throughout reaction. This improves catalytic efficiency selectivity, establishing dual-catalytic functionality material biosensing applications.
