    "abstract": "Total antioxidant capacity (TAC) assessment is vital for evaluating food nutritional quality, yet conventional methods face limitations in complex matrices, efficiency, and environmental robustness. To address this, we synthesized manganese-doped porous carbon nanospheres (Mn@CNS), which feature a high density of uniformly distributed diverse catalytic sites, creating an efficient peroxidase-like nanozyme for sensitive colorimetric detection of TAC. Kinetic analysis revealed that Mn@CNS had strong affinities for both 3,3',5,5'-tetramethylbenzidine and H",
