Nanorobots Complete First Human Vascular Surgery: Biodegradable Micro-Robots Clear Blood Clot
ETH Zurich team completed the world's first nanorobot vascular surgery, with magnetically controlled nanorobots clearing a deep vein thrombosis in 30 minutes without complications.
Nanorobots Complete First Human Vascular Surgery: Biodegradable Micro-Robots Clear Blood Clot
ETH Zurich's Nanorobotics Lab announced on March 4 that its magnetically controlled nanorobots completed the world's first human vascular clearance surgery. A 62-year-old patient with deep vein thrombosis had the clot in their leg completely cleared during a 30-minute minimally invasive procedure.
The nanorobots are just 200 micrometers in diameter, made from biodegradable polymers, and navigated through blood vessels using external magnetic fields. Upon reaching the clot, the plasmin carried on the robot surface directly dissolved the thrombus. Within 30 days post-surgery, the robots biodegrade into harmless substances in the body.
Lab director Professor Brad Nelson said: 'Compared to traditional thrombolytic drugs, nanorobots' advantage is precision — they act only at the clot site without causing systemic bleeding risks.' The team plans to launch a larger clinical trial within 2028.
