(A–F) Characterization of nanofullerol. Analysis of the ultraviolet-visible (UV-vis) spectrum (A), size distribution (B), and surface charge (C) indicated that the aqueous nanoparticles of fullerol had a characteristic absorption peak at 293 nm, a narrow size range of 25–45 nm, and a negative surface charge from −40 mV to −60 mV. The insert in (C) illustrates the chemical structure of fullerol. Nanofullerol was also proven to be able to scavenge various reactive oxygen species, including superoxide anions (D), hydroxyl radicals (E), and nitric oxide (F).

Abbreviations: SOD, superoxide dismutase; Abs, absorbance.
