However, both direct endotoxin detection in and removal from protein-rich fluids remains challenging. We present the synthesis and functionalization of ultra-magnetic cobalt/iron alloy nanoparticles and a magnetic separation-based approach using polymyxin B-functionalized nanomagnets to remove endotoxin from human blood in vitro.

The specific removal of these disease-causing factors from a patient's blood would be in many cases the most direct way of cure. But current blood purification methods are not applicable to specifically and efficiently remove larger biomolecules such as bacterial toxins or antibodies directly from a patient's blood.
