Future Tech: Bloodstream Robots

You remember the movie Innserspace, right? You know, with Dennis Quaid and Martin Short, where Quaid gets shrunk down and injected into Short? Yeah, that one. Well believe it or not, that wasn’t too far off from the idea behind nanotechnology. More specifically, bloodstream robots.

These little guys can be used to fight off everything from diseases, to strengthening the bodies immune system. The technology has been around for a while, but it’s only been in recent years that scientists have been able to test it. In Montreal, they’ve created a type of nanobot where live, swimming bacteria is coupled with polymer beads. One application could be used to destroy a lung tumor, as the scientists successfully steered the bots though the carotid artery of a living pig using magnetic resonance imaging. Further research shows that they are able to do this on humans, too.

With leaps like, it’s only a matter of time before the medical field takes a hold of this technology, and starts using it to deliver things like cancer-killing drugs. While it may still be in the early stages of development, nanobots that are able to swim through the blood may just be the next step in curing what was once an incurable disease, prolonging human life.

While you may not like the idea of having tiny robots injected into your body, just remember that Dennis Quaid did return to normal, and the story had a happy ending.
