Stylised bright blue fish on background of pale blue plastic waste.

A robotic fish that removes microplastics from water has been developed by researchers at Sichuan University, China.

Organic dyes, antibiotics and heavy metals in microplastics attach themselves to the self-propelled robo-fish, reports The Guardian in Scientists unveil bionic robo-fish to remove microplastics from seas.

Although still at the test stage and only able to move on the water surface, the development is seen as another tool that could help tackle the scourge of plastic in the marine environment.
