This involves the blood of patients being mixed with magnetic iron particles, which bind the bacteria to them after which they are removed from the blood using magnets. The initial laboratory tests at Empa in St. Gallen have been successful, and seem promising.

Blood poisoning is still fatal in more than 50% of cases, but can be cured if treated at an early stage. The highest priority is therefore to act quickly. For this reason, doctors usually administer antibiotics even in the event of a suspicion of blood poisoning, without first ascertaining whether it is actually a bacterial sepsis, which in turn greatly increases the risk of resistance to antibiotics developing.
