Nanozyme-based synergistic therapeutic strategies against tumors.

Cancer remains a global health threat, with traditional treatments limited by adverse effects and drug resistance. Nanozyme-based catalytic therapy with high stability and controllable activity provides targeted and specific in situ tumor treatment to address these challenges. More intriguingly, the tremendous advances in nanotechnology have enabled nanozymes to rival the catalytic activity of natural enzymes, presenting an exciting opportunity for innovating antitumor nanodrugs. This review systematically summarizes the latest progresses in nanozyme-based anticancer catalytic therapy, with a particular focus on various synergistic antitumor strategies, including other functional enzymes, drugs, exogenous stimuli and radiotherapy. These combinations not only enhance the efficacy of cancer treatment and reduce systemic toxicity but also offer insights into the development of potent antitumor nanodrugs.
