Toxicity test method

Suspension preparation method
400 mg MWNT-OH powder was added to 400 mL ultrapure water generated by a Barnstead EPure system (Thermo Fisher Scientific, Waltham, MA) in a 500-mL glass beaker. The mixture was sonicated in an ice bath with a sonicating probe (Vibra-Cell VCX 500, Sonics & Material, Newtown, CT) at 100 W for 30 min. The sample was stored at room temperature in a 500 mL clear glass bottle wrapped in aluminum foil before use within 6 months.

Particle size measurement method

ENM electrophoretic mobility measurement.
