Preparation of a high dispersibility graphene oxide (GO) that can be reliably used in biological investigations is reported by Kostas Kostarelos and co-workers on page 433. Exposure of cells and tissue to the graphene oxide indicated a lack of cytotoxic responses in human cell cultures (in vitro) and after injection to living animals (in vivo).
