Iron-based nanozymes are promising for tumor catalytic therapy owing to their biocompatibility and peroxidase-like activity, but the concurrent catalase-like activity undermines the therapeutic efficacy. Here, the authors address this issue by developing a hemin–cysteine–Fe nanozyme, which exhibits catalytic selectivity and exclusive peroxidase-like activity.
