Toxicity test method

Suspension preparation method
10 mg / 50 mg RGO was added to 10 mL/50 mL ultrapure water generated by a Barnstead EPure system (Thermo Fisher Scientific, Waltham, MA) in a 10 -mL / 50 -mL centrifuge tube, and sonicated in a sonicating cup horn (sonics & Material, Newtown, CT) at 100 W for 30 min. The samples were stored at room temperature in 10 -mL / 50 -mL centrifuge tubes wrapped in aluminum foil before use within 6 months.

Particle size measurement method

ENM electrophoretic mobility measurement.
