Sepsis is a life-threatening misguided immune response to an infection. Affecting 50 million people per year, it is one of the greatest global health challenges and is responsible for 20% of all deaths due to the lack of effective treatments.

hemotune AG, a medical device spin-off company from ETH Zurich, is developing a disruptive blood purification technology based on nanoengineered magnetic beads. The goal is to restore immune balance in sepsis and improve patients’ outcomes by selectively removing multiple key compounds directly from the blood.
