New blood ‘clean’ uses magnets to pull out deadly diseases

UK engineer devises a way to bind tiny magnetic particles to a specific disease and then simply suck it out

Deadly conditions including leukaemia, sepsis and malaria could be drawn from the body using magnets, after a British engineer designed a blood-filtering system that sieves away disease.

Dr George Frodsham came up with the idea while studying how magnetic nanoparticles can be made to bind to cells in the body, to allow, for example, those cells to show up on scanners. But he realised that if it was possible to magnetise cells for imaging, it should also be possible to then suck them out of the blood.

In theory, any bacterial infection, blood cancer or virus that could be grabbed by a tiny magnetic particle could be removed from the body without the need for lengthy treatments with harsh drugs...
