Functional group density on the surface of the GO/RGO sheets plays a key role in cell toxicity. It may be possible to reduce the toxicity of GO and RGO and allow their wide range potential in biomedical-applications by masking the oxygenated functional groups using a biocompatible polymer or manipulating the surface functional groups.
