Raman spectroscopy for the detection of organ distribution and clearance of PEGylated reduced graphene oxide and biological consequences

Graphene, a 2D carbon material has found vast application in biomedical field because of its exciting physico-chemical properties. The large planar sheet like structure helps graphene to act as an effective carrier of drug or biomolecules in enormous amount. However, limited data available on the biocompatibility of graphene upon interaction with the biological system prompts us to evaluate their toxicity in animal model. In this study organ...
