Researchers have created autonomous particles covered with patches of protein “motors.” They hope these bots will tote lifesaving drugs through bodily fluids.
THERE’S ALWAYS BEEN something seductive about a nanobot. Comic books and movies implore you to imagine these things, thousands of times thinner than a human hair and able to cruise around a body and repair a bone or heal an illness. (Or, if they’re more nefarious, simply explode.) Their scale is unfathomably finite. Their possibilities, sci-fi will have you believe, wildly infinite. While that incongruity makes it perfect for the denizens of a writers’ room figuring out how to kill James Bond, it’s also a sort of curse. Surely we can’t take tech like this seriously. Can we?
It turns out, the nanobots are among us.
