TScientists believe that simple magnetic coils, half the width of a human hair, could help cope with the scourge of microplastic pollution in the Earth's oceans.
The coils, which resemble bed springs under a microscope, were invented by researchers from Adelaide and Curtin University in Australia.
Each is covered with nitrogen and a magnetic metal called manganese. Together, they react to create oxygen molecules that attack the plastic and help break it down.
During the tests, the team added the reels to samples of contaminated water. They tested the water eight hours later and found a reduction of 30 to 50% in microplastics.
Without coils, microplastics could take decades to decompose naturally.
