5723 797 Au25(p-MBSA)18 This pH-dependent peroxidase-mimicking activity is expected to have broad application prospects for Au25(p-MBSA)18 in the biomedical field. For example, in tumor cells with acidic pH,(33) Au25(p-MBSA)18 is expected to be stable, and it can increase the production of intracellular •OH to induce tumor death.
