Magnet-controlled microrobots deliver drugs precisely
Magnet-controlled microrobots deliver drugs precisely within the body, dissolving to release cargo.
Why it matters
- New technology could improve drug delivery and reduce side effects.
- Potential for use in stroke treatment and other localized therapies.
By the numbers
- 12 million: annual global strokes.
- 95%: success rate in delivering drugs to target locations in tests.
- 4 mm/s: speed of microrobot along vessel walls.
- 20 cm/s: speed against blood flow.
The big picture
- Microrobots use magnetic fields for navigation and control.
- Three strategies allow navigation through various blood flow conditions.
- Technology aims to be ready for clinical use soon.
What they're saying
- Comments show curiosity and hope for medical applications.
- Some question whether it qualifies as a robot.
Caveats
- Tests were in models and animals; human trials needed.
What’s next
- Human clinical trials are the next goal.
