Graphene is not antibacterial

What is it about?

Produced graphene sheets are not cytotoxic or antibacterial. We have demonstrated that large graphene sheets with thickness 2 and 5 layers dont produce reactive oxygen species.

Why is it important?

Despite initial enthusiasm about potential use of graphene as antibacterial agent, the progress in their development is still in its infancy. One of the main reasons is an inadequate understanding of graphene structure - antibacterial function correlation with respect to different modifications required to provide water dispersibility. There is a huge disagreement in scientific community about dominant mechanism of graphene toxicity or lack of it.
