'A significant threat': These tiny 'trained' robots can catch invisible plastic dust in your drinking water
Nanoplastics in drinking water pose a significant health risk due to their ability to bypass conventional filters and enter human organs. Researchers at Brno University of Technology have developed electrostatic nanorobots that actively seek and capture these tiny plastic particles. The robots use magnetic control and porous hexagonal rods to trap nanoplastics without requiring fuel or light.
- ▪Nanoplastics are small enough to pass through traditional water filters and can accumulate in human organs.
- ▪The nanorobots use electrostatic attraction to bind to nanoplastics, similar to how a balloon sticks to hair.
- ▪Each nanorobot is made of iron-based metal-organic frameworks with pores that capture plastic particles.
- ▪Magnetic guidance allows the robots to move precisely through water without external energy sources like light or fuel.
- ▪The study detailing this technology was published in the journal Environmental Science: Nano.
