Investigation on the use of graphene oxide as novel ...

2015-5-8 · This paper presents a unique synergistic behavior between a graphene oxide (GO) and graphene nanoplatelet (GnP) composite in an aqueous medium. The results showed that GO stabilized GnP colloid near its isoelectric point and prevented rapid agglomeration and sedimentation. It was considered that a rarely encountered charge-dependent electrostatic interaction between the highly …

NF-κB-related decrease of glioma angiogenic …

Due to the intensive endocytosis of NG and graphene oxide nanoplatelets (nGO) by glioma cells, it is hypothesized that nGO and NG will decrease intracellular ROS 13. Moreover, it is assumed that this will decrease NF-κB-dependent proangiogenic cytokines in a p53 wild-type glioma cell line (U87) but not in a p53 mutant cell line (U118).
