Cytotoxicity of BP nanodots against C2C12 skeletal myoblasts. a C2C12 skeletal myoblast viability after the 24 (■) and 48 h (△) of incubation with various concentrations of BP nanodots (0 to 250 μg/mL). b Representative optical microscopic images of C2C12 skeletal myoblasts cultured with BP nanodots (0, 0.5, 4, and 250 μg/mL) for 24 h. The viability of C2C12 myoblasts was determined using a CCK-8 assay, and all photographs shown in this figure are representative of six independent experiments with similar results
