Bacteria Create Better Graphene

Bacteria Create Better Graphene
An innovative method of using bacteria to create graphene reduces the need for harsh chemicals.

The technique from researchers at Rochester University involves first creating a batch of graphene oxide, which is easy to produce but offers less conductivity due to the oxygen groups it contains. However, when the team then added the Shewanella bacteria to the mix and let it sit overnight, the bacteria removed most of the oxygen and rendered the material into a more useful graphene. The greener bacteria process was also found to produce a higher quality graphene with an increased storage time.
