Magnetic Nanobeads Can Snatch Bacteria and Virus Out of Blood

Sepsis is an nasty and surprisingly common way to die. The illness is triggered by blood infections but, ultimately, it's your own immune reaction--not the bacteria or virus--that poisons you to death. Filtering those pathogens out of blood right away, though, could be a promising treatment. Enter a new device made of magnetic nanobeads coated in sticky proteins that attract bacteria, viruses, and fungi.
