Scientists Create Robot Fish That Collect Microplastics

Scientists at Polymer Research Institute of Sichuan University have invented tiny, self-propelled robot fish that can be programmed to remove free-floating microplastics from the sea by latching onto and absorbing them into its self-healing body. Inspired by nacre, commonly referred to as mother of pearl, researchers set out to create a similar sea-worthy material. They did so by “layering various microscopic sheets of molecules according …
