• 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

• antioxidant capacity. The antioxidant activity of 12 fullerene esters (as water soluble fullerosomes, obtained by liposome formation with soybean lecithin [31]) was determined by FOX antioxidant assay [32], using vitamin C and fullerene C60 as reference compounds. The FOX assay is based on the oxidation of
