Doctors can now sift bacteria from your blood using magnets
A joint research effort between Harvard University, the Empa research group and Adolphe Merkle Institute has resulted in a novel means of purifying blood: they simply suck the bacteria out with magnets. First, the researchers coated antibodies that bind to harmful bacteria with iron particles. When exposed to the bacteria in a solution, the antibodies did what they do and latched on to them. When the solution was subsequently passed through a dialysis machine, magnets literally pulled the antibodies -- and their pathogen passengers -- out of the blood, leaving it clean....
