An award-winning engineer has developed a new technology that could draw deadly infections such as malaria and sepsis from the body using magnets. ================================================================ George Frodsham designed the blood filtering system whilst studying how magnetic nanoparticles can bind to cells to make them detectable during imaging. He realized that if the nanoparticles can be made to magnetize cells so that they show up on scanners, it should also be possible to use them to draw cells from the blood. “In theory, you can go after almost anything” Theoretically, any bacteria, virus, or blood cancer, such as leukemia, could be bound...
