Researchers had excitedly turned to the material to
discover graphene’s potential applications, since it was first
isolated with the help of Scotch tape in 2004 [19]. Graphene
and graphene oxide (GO), with extraordinary mechanical

properties (high Young’s modulus and hardness and excel-lent flexibility) [20], high specific surface area, and low
cost, have been considered to be effective reinforcements
for high-performance composites [21–24]. On the other
hand, GO contains a number of oxygen-containing groups,
which makes it relatively easy to be dispersed into some
polar solvents and form intercalated composites with polar
molecules through the strong interaction [25–30]. Recently,
graphene and GO have been proved to exhibit excellent
biocompatibility and high antibacterial activity [25, 30–34].
These have motivated us to explore the possibility of GO
as an antibacterial reinforcement in biomaterials and study
the antiseptic properties and cytotoxicity of GO-containing
composites
