Paper entitled: Nose-to-Brain Translocation and Cerebral Biodegradation of Thin Graphene Oxide Nanosheets:
Thin graphene oxide sheets can translocate from the nasal cavity to the brain
Translocation is size dependent, with ultrasmall nanometric sheets translocating the most
Kinetics of graphene oxide accumulation are time dependent and brain-region-specific
Brain-accumulated graphene oxide undergoes changes consistent with biodegradation
