Photothermal and degradation properties of FA-BSA-PEG/MoOx nanosheets. A The temperature heating curves of nanosheets with different concentrations; B temperature variations of nanosheets solution under continuous laser irradiation for five on–off cycles; C temperature rise and fall curves of nanosheets with laser on/off; D photothermal conversion fitting curve of nanosheets; E degradation process of MoOx-PEG incubated in PBS with different pH values and F digital photos; G TEM images of nanosheets after 2 h degradation at pH 5.0, 7.4 and 11.4 PBS solution, respectively; scale bar: 0.6 μm; H the degradation curves of nanosheet in serum with different pH values (5.0, 7.4) over time
