🔬 Tiny silver-coated microrobots, powered by ultraviolet light, can swim upwards and break down antibiotic pollution in water.

💧 In laboratory tests, these Janus microrobots removed 88% of tetracycline in 90 minutes, and achieved 82% degradation in real wastewater.

✨ The technology combines self-propulsion with photocatalysis, using silver-enhanced graphitic carbon nitride to generate reactive oxygen species that degrade contaminants.
