Figure 6.

Transmission light microscopy and fluorescence microscopy of MG-63 and hMSC cells after 2 h of incubation with LA (2.0 μg mL⁻¹) and C₆₀ + LA mixture (1.5 + 2.0 μg mL⁻¹). The blue fluorescence indicates the co-localization of LA and C₆₀ + LA nanocomplex on the cells. Note that C₆₀ fullerene alone is not fluorescent. Scale bar 20 µm.
