Quatum Dots in the Brain?->
particles. Researchers at the University of Washington have discovered
that when these particles are in proximity to a nerve cell, shining
light on the dots causes the neurons' ion channels to open and the
nerve cell to fire. This opens up a new vista of possible treatments for
various brain disorders. The dots can be implanted by coating them with
molecules with an affinity for the targeted tissues and injecting them
into the bloodstream. After that, the main problem will be to figure out
how to shine light into the brain. But there are high hopes for the
treatment of retinal disorders, where this problem is, obviously,
already solved."
