A 0 means no activity, a hyphen indicates low anti-angiogenic activity, and two hyphens indicate medium anti-angiogenic activity. Values with different letters are significantly different, P < 0.05. SE, standard error; GNS, graphene nanosheets; NG, graphite nanoparticle; ND, diamond nanoparticle; C60, fullerene C60; MWNT, multi-wall nanotube.
