Functional characterization of the synthesized water-soluble C60(OH)46 fullerenol. a Low-magnified TEM image and b HR-TEM image of a water-soluble fullerenol illustrating the materials {1\( \overline{1} \)00} lattice planes and the mean size of 1.11 ± 0.03 nm with a d-spacing of 0.213 nm. c UV–vis and d FTIR spectra of nanomaterial. e Deconvoluted C(1s) XPS spectra and fitted peaks obtained using Gaussian function: nonoxygenated ring (C–C/C=C), C–O bond, and C=O bond, respectively. The atomic ratio and bonding composition of fullerenol are shown as summarized in the table. The O(1s)/C(1s) atomic ratio is 35.8%
