Nanozymes, which are nanomaterials that replicate the catalytic activities of natural enzymes in biological systems, have recently demonstrated considerable potential in improving cancer immunotherapy by altering the tumor microenvironment. Nanozyme-driven immune responses represent an innovative therapeutic modality with high effectiveness and minimal side effects. These nanozymes activate the immune system to specifically recognize and destroy cancer cells. Combined with immunotherapeutic agents, nanozymes can amplify the anti-cancer effectiveness by integrating immune remodeling with immunogenic cell death (ICD). This review offers a thorough discussion about various nanozymes involved in anti-cancer immunity, including those mimicking catalase (CAT), superoxide dismutase (SOD), peroxidase (POD), and oxidase (OXD). It also discusses the challenges and future directions for translating nanozyme platforms into clinical applications, enhancing the susceptibility of cancer cells to immunotherapy. Nanozyme-based strategies have substantial potential in oncology, offering new and effective therapeutic options for cancer management.

Nanozymes, as superior alternatives to natural enzymes, frequently employ the inhibition effect in turn-off sensors for analyte detection. However, limited attention has been paid to the inhibition mechanisms between analytes and nanozymes, limiting advancements in nanozyme-based sensing. Benefiting from the synergistic effects between three-dimensional network structure of aerogel and ligand effect triggered electronic regulation, PtBi aerogel nanozymes (PtBi ANs) exhibit superior peroxidase-like activity (293.

Nanozymes, nanomaterials with intrinsic enzyme activity, have garnered significant attention in recent years due to their catalytic abilities comparable to natural enzymes, cost-effectiveness, high catalytic activities, and stability against environmental fluctuations. As functional analogs of natural enzymes, nanozymes participate in various critical metabolic processes, including glucose metabolism, lactate metabolism, and the maintenance of redox homeostasis, all of which are essential for normal cellular functions. However, disruptions in these metabolic pathways frequently promote tumorigenesis and progression, making them potential therapeutic targets.
