Figure 5. Abiotic ROS generation by fumed silica nanoparticles.

Figure 5

Hydroxyl radical generation by (A) Ti- and (B) Al-doped fumed silica nanoparticles was determined by the APF. 100 μg/ml of non-doped and doped fumed silica nanoparticles were incubated with 10 μmol/L of APF (in PBS) in a volume of 100 μL in a 96-well plate at room temperature for 6 h. Fluorescence was collected at wavelength of 480–600 nm with an excitation wavelength at 455 nm in a microplate reader.
