Evaluation of the structure-activity relationship of carbon nanomaterials as antioxidants.

Aim: To develop the potential application of carbon nanomaterials as antioxidants calls for better understanding of how the specific structure affects their antioxidant activity.

Materials & Methods: Several typical carbon nanomaterials, including graphene quantum dots and fullerene derivatives were characterized and their radical scavenging activities were evaluated; in addition, the in vitro and in vivo radioprotection experiments were performed.

Results: These carbon nanomaterials can efficiently scavenge free radicals in a structure-dependent manner.
