Characterization and evaluation of the free radical scavenging performance of fullerenols. A) hydrodynamic size of fullerenols (insert: TEM image, scale bar 100 nm). B) FTIR spectrum of fullerenols. C) Raman spectrum of fullerenols. D) DPPH radical scavenging ability of fullerenols. E) ABTS radical scavenging ability of fullerenols. F) ONOO− scavenging ability of fullerenols. G) •OH scavenging ability of fullerenols. H) O2•− scavenging ability of fullerenols. I) UV–vis absorption spectra of fullerenols treated with and without UV irradiation (15 W, 1 h).
