Toxicity of pristine versus functionalized fullerenes: …

WebPristine graphene was found to accumulate on the cell membrane causing high oxidative stress leading to apoptosis, whereas carboxyl functionalized hydrophilic graphene was internalized by the cells without causing any toxicity. This article is part of the themed collection: Nanoscale 10th Anniversary: Top Cited Articles WebThe key determinant of the toxicity and biocompatibility of graphene is the chemical nature of groups bonding to its surface. The hydrophobic pG is more toxic than hydrophilic GO, because GO is taken up by cells and internalized. 32 This toxicity is caused by the affinity of pG to lipids, which form cell membranes. twitch movies list
