Microrobots to clean teeth

Caption

Arranged in bristle-like structures, a robotic microswarm of iron oxide nanoparticles developed by a team from the University of Pennsylvania effectively cleaned plaque from teeth. The nanoparticles have both magnetic and catalytic properties; catalyzed hydrogen peroxide produced free radicals that eliminated tooth decay-causing pathogens as well.
