Robot attracting particles in water.

• Tiny robots actively chase nanoplastics instead of waiting for contact
• Electrostatic attraction lets nanobots grab plastic-like charged surfaces
• Magnetic control allows precise movement without fuel or light

There is a lot of plastic waste in the world, which is endangering the environment, and tiny particles of these plastics are now contaminating drinking water.
