• ). Graphene oxide sheets (GOS) were synthesized via a modified Hummer's method and were characterized by X-ray diffraction (XRD), ultraviolet–visible spectroscopy (UV), and transmission electron microscopy (TEM). The method of Zhang was adopted for cracking of GOS. Then nano-graphene oxide was PEGylated with

• increased OS even after 4 h. In conclusion increased OS induced by PEG-nGO could be detrimental to brain, heart and kidneys.

• of PEGylated nano-graphene oxide (PEG-nGO), and examined the recovery of the organ from the stress after specific intervals of time. For this purpose, we oxidized sheets of graphite with an improved Hummer's method [3]. Afterward, GO sheets were cracked into nGO by a previously adopted method by
