What to know about Nanotechnology

Researchers from the Czech Republic have developed magnetic MXene-based microrobots capable of removing microplastics from soil and water in laboratory settings. The study, published in npg Asia Materials, demonstrates high removal rates for polystyrene and PET particles, though the authors note that field trials and risk assessments are still required.

Why it matters

They damage soil fertility, disrupt nutrient cycling, harm aquatic and terrestrial life, and can move through the food chain.

Common ground

That makes cleaning them up an urgent priority.

Claim 2: “In the model soil, they removed about 81% of the polystyrene and 72% of PET.”

DISPUTED

Two sources ('Swarms of tiny robots remove microplastics from soil and water' and 'Magnetic Microrobots Remove Microplastics from Water and Soil') state 81% polystyrene and 72% PET. However, another source ('Scientists May Have Found a Way to Remove Microplastics From Soil...') states 81% polystyrene and 89% PET.
