Engineers at Washington University have discovered a new technique that could change drug delivery to the brain. They were able to apply a nanoparticle aerosol spray to the antenna of locusts, then track the nanoparticles as they traveled through the olfactory nerves, crossed the blood-brain barrier and accumulated in the brain. This new, non-invasive approach could someday make drug delivery as simple as a sniff for patients with brain injuries or tumors.
