Summary

Story summary

Researchers at ETH Zurich have developed tiny magnetic microrobots that deliver drugs to blood clots with 95% tested success, addressing roughly 12 million stroke patients annually.
The microrobots are controlled externally by magnetic fields and release medication precisely where needed.
Initially focused on stroke treatment, the technology shows potential for targeting tumors and infections.
The team plans human trials soon.
The study was published in Science on November 13, 2025.
