• voltammetry; FOX assay; fulleropeptide esters; scanning electron microscopy; Introduction Their highly π-conjugated, spherically shaped, hydrophobic character and their unique physicochemical, electronic and magnetic properties make fullerenes attractive building blocks for chemical modifications, providing

• essential antioxidant capacity, which is mainly attributed to the electron-accepting properties of the fullerene unit. The self-assembly characteristics of fulleropeptide esters 2–12 were studied by SEM on the samples prepared by a drop–drying process [2] and on the solid samples. In order to examine the

Additionally, SEM micrographs (Supporting Information File 1, Figure S1, insets) have clearly revealed network-like structures of three fulleropeptide esters, 9, 11, and 12, obtained at this concentration, indicating the morphology dependence of the investigated compounds on the peptide
