A Schematic illustration of the MoO3-x NUs with multi-enzyme mimicking activities for pH-responsive tumor therapy. B Electron paramagnetic resonance spectra of MoO3-x NUs in the presence of H2O2 (1 mM). C DPBF degradation curves at different pH conditions (pH 6.0, pH 7.4, and pH 8.5). D Cytotoxicity of MoO3-x NUs against B16 melanoma cells at pH 7.4 and pH 6.0; E B16 xenograft tumor growth curves after different treatments (n = 5) [89].
