Cracking the blood-brain barrier with magnetic nanoparticles

Blood-Brain Barrier

The blood-brain barrier, the thorn in the side of medicine. It makes using drugs directed for the brain ineffective at best and unusable at worst. This barrier runs inside almost all vessels in the brain and protects it from elements circulating in the blood that may be toxic to the brain. This barrier means that currently 98% of therapeutic molecules are also unable to cross to the brain. However, researchers now say magnetic nanoparticles can open the blood-brain barrier and deliver molecules directly to the brain.

The blood brain barrier, it can be very picky about who [or what] can come in.

Ever wonder why you don’t see too many illnesses that affect the brain directly? You can give your head a nice pat and congratulate the blood brain barrier for keeping the bad out and letting the good in. Unfortunately the blood brain barrier can be, well a barrier, or more like a bouncer– especially when it comes to new drugs that could potentially help treat issues with the brain.

The blood-brain barrier helps that finicky brain of yours maintain the delicate environment that it needs to thrive. There’s just one problem: The barrier is so good at what it does, it won’t let medicines pass through. Like most things with the brain, we don’t know enough about it to control it for our benefit.
