Tiny Robots Are Fishing For Microplastics

There are plenty of fish in the sea. Some are big, and some are small. Some are slow, and some are skittish. Some are bold and bright. And some are actually fish-shaped robots, made to absorb microplastics. A new study in Nano Letters reveals that researchers recently developed a tiny robot that looks and moves like a fish, collecting detrimental plastic particles as it swims through the water.
