Based on our work, the researchers can choose graphene products (graphene paper, graphene film, graphene foam or graphene fiber) efficiently according to the research object in the future.
This work opens up a whole new vista on how to disperse graphene.
It is evident how investigating the graphene toxicity is of fundamental importance in the context of medical purposes.
In addition, the electrolyte can be used to gate the graphene; i. e., a dual-gate structure is realized.
The superior electrochemical performance of the I-doped graphene is explained by the change of graphene lattice, defects and positive charge density introduced by the doping of I atoms.
These results therefore demonstrate how the peculiar properties of graphene extend also to the behavior of its nonequilibrium carriers.
We demonstrate how the dopants, combined with oxygen-containing groups alter the reactivity of graphene towards Na.

Although literature reports have mixed findings, we emphasize that the key question is not how toxic graphene itself is, but how to modify and functionalize it and its derivatives so that they do not exhibit acute/chronic toxicity, can be cleared from the body over time, and thereby can be best used for biomedical applications.
We show how IBS can be used to successfully exfoliate graphite into few-layers graphene yielding highly stable dispersions in water.
These data show how the presence of nitrogen atoms in the graphene network modifies the electronic interaction of organic molecules with graphene.
