Ultrasound Implant Safely Opens Blood–Brain Barrier
The cells lining blood vessels in the brain form tight, tough-to-penetrate junctions that prevent toxic molecules from slipping into the brain.
Unfortunately, this blood-brain barrier also blocks cancer drugs from reaching tumor cells in the brain, creating a significant drug-delivery problem.
Now, preliminary results from a Phase I/II clinical trial suggest that a small implant that emits ultrasound waves can safely open the blood-brain barrier in people, potentially allowing drugs in.

Glucose, bicarbonate soda, and others all traverse this barrier happily. How to reproduce this blood/brain barrier for other use cases outside the body, could be very interesting. Or being able to create such a barrier for clean vs unclean water would be really something.
