Researchers have created microscopic robots that can rapidly navigate through liquid environments, collect bacteria, and deposit them in specific locations. These tiny devices are powered by light, which allows precise control over their movement and cargo delivery. The technology could have significant applications in environmental monitoring, where it might help track bacterial contamination in water supplies, or in biotechnology, for targeted delivery of microorganisms to industrial processes. The ability to manipulate such small-scale systems opens up new possibilities for precision in fields ranging from medicine to ecology.
