Nano-devices that cross blood-brain barrier

In my upcoming sci-fi novel NexusI write about a nano-device that can cross the blood-brain barrier and which has a very real impact on the mind.  Not so far fetched…

A team of scientists from Johns Hopkins and elsewhere have developed nano-devices that successfully cross the brain-blood barrier and deliver a drug that tames brain-damaging inflammation in rabbits with cerebral palsy.

via Nano-devices that cross blood-brain barrier open door to treatment of cerebral palsy, other neurologic disorders.
