Revolutionary microbots combat sinus infections
Scientists in China have built microrobots, smaller than dust, that can hunt down and destroy tough sinus infections.
Guided by magnets and activated with light, these bots target bacteria directly—skipping the need for antibiotics or surgery.
Microrobots wipe out bacteria in animal tests
In animal tests, doctors steered the microrobots right to infection spots using magnetic fields.
Once there, a quick burst of light made the robots heat up and release reactive oxygen species, wiping out over 99% of bacteria without hurting healthy tissue.
Future possibilities of this technology
The team hopes to use this tech for other hard-to-treat infections in places like the lungs or digestive system.
If it works in humans, it could be a game-changer for fighting antibiotic-resistant bugs—no pills required.
