Foreign Media: A team from the Qinghai Salt Lake Research Institute, Chinese Academy of Sciences, has developed a light-driven metal-organic framework micro-motor capable of autonomously swimming in water and capturing uranium ions.
The material has a diameter of only 2 micrometers and, after chemical structural modification, can remain stably suspended in water for long periods. Its mechanism is inspired by "predators" actively searching for targets. Seawater contains approximately 4.5 billion tons of uranium, but its concentration is extremely low, making extraction difficult and costly. With China's expanding nuclear power industry, the country heavily relies on imported uranium resources. This technology holds strategic significance for ensuring self-sufficiency in nuclear fuel supply and mitigating radioactive pollution.
