In vitro and in vivo effects of graphene oxide and reduced graphene oxide on glioblastoma

International Journal of Nanomedicine, 2015
Graphene and its related counterparts are considered the future of advanced nanomaterials owing to their exemplary properties. However, information about their toxicity and biocompatibility is limited. The objective of this study is to evaluate the toxicity of graphene oxide (GO) and reduced graphene oxide (rGO) platelets, using U87 and U118 glioma ...

Morphological and structural properties in graphene oxides and reduced graphene oxides

Revista de Investigación de Física, 2019
In this work, graphite powder was used as initial material to obtain graphene oxides (GO). We propose the reduction of graphene oxides, by physical-chemical method, which consists in a thermo and chemical reduction in the presence of NaBH4 to obtain reduced graphene oxides (RGO).
