A British engineer has found a way to filter unwanted cells from blood using magnets — and his tool could be used in clinical trials as soon as next year.
Thanks to existing research, biochemical scientist George Frodsham knew it was possible to force magnetic nanoparticles to bind to specific cells in the body. But while other researchers did so primarily to make those cells show up in images, he wondered whether the same technique might allow doctors to remove unwanted cells from the blood.
“When someone has a tumour you cut it out,” he told The Telegraph. “Blood cancer is a tumour in the blood, so why not just take it out in the same way?”
