        1A group of Chinese scientists say that they have developed a robotic fish which can remove microplastic particles from water environments.Researchers who are working on the project say that these robots can help to clean up plastic pollution in oceans around the world.

        2Microplastics,pieces of plastic smaller than 5 millimeters,are large in quantity and widely distributed in the oceans.They are easily eaten by marine organisms and transmitted through the food chain,presenting a serious threat to human and ecosystem health.

        3The robotic swimmers,which are made of a soft chemical compound,are about 1.3 centimeters long.According to the researchers,such robots are designed to absorb microplastics while moving through the water.

        4The project was launched by a team at Sichuan University in southwestern China.The researchers said the robots had already performed well in shallow water and they planned to carry out more tests in deeper waters.

        5The robotic fish were built to target microplastic particles,which are smaller than 5 millimeters.Studies have confirmed that microplastic pollution has been discovered inmany natural environments.The material comes from the breakdown of manufactured plastic products and industrial waste.

        6The team said the robots can be controlled by light.Turning“a near-infrared light laser”on and off causes the fish's tail to move back and forth.The robotic fish can swim up to 2.76 body lengths per second.The researchers said this is faster than most similar soft robots.

        7Wang Yuyan was a member of Sichuan University's research team.She said that the small,lightweight robot is currently being used to collect microplastics for research purposes.But Wang added that the team plans to expand that use so that the robot fish can remove larger amounts of microplastic waste from deep ocean areas.

        8“The fish can take in different kinds of microplastics and even repair itself when damaged,”the researchers said.“And if a robot fish is accidentally eaten by a real fish,the real fish could safely digest the material,”the team added.Wang said similar robots could be developed to be placed inside the human body to remove unwanted materials or diseases.
