Nanomagnets clean blood
Nanoparticles latch onto toxins in blood but are magnetically trapped before they can enter the body
The group used their extracorporeal circuit to remove lead and the drug digoxin from the blood of rats. Target compounds in blood adhered to the nanoparticles as they collided within the circuit. The nanoparticles were then collected by magnetic separation with the toxin immobilised on the particle surface before blood could re-enter the body.
