Microrobots Deployed to Clean Water by Capturing Microplastics and Bacteria

Innovative swarms of microrobots effectively remove pollutants from water, offering a reusable solution to combat environmental hazards.

Researchers developed microrobots that attract and capture microplastics and bacteria, addressing dual threats in aquatic environments.
The robots, measuring 2.8 micrometers, mimic natural swarms and can be controlled via a magnetic field.
In lab tests, high concentrations of these robots removed about 80% of targeted bacteria and significantly reduced microplastics.
Post-cleanup, robots are decontaminated using ultrasound and UV radiation, allowing for their reuse.
The technology, still in development, promises significant environmental benefits and is funded by various European programs.
