From: Effects of Pin-up Oxygen on [60]Fullerene for Enhanced Antioxidant Activity
Plots of the ratio of β-carotene bleaching rates in the presence (R f) or absence (R 0) of fullerene antioxidants R f/R 0 versus ratio of concentration [fullerene]/[β-carotene] for PVP-entrapped C60, C60O, and C60On. The slope of each linear regression line corresponds to the relative radical scavenging rate constant k rrs relative to that of β-carotene. The dotted horizontal line indicates the value in the absence of antioxidants as a control
