McGill team tests 'click clotting' to halt bleeding in seconds
Montreal researchers at McGill University have developed 'click clotting,' a chemical approach using a patient’s own or donor blood to rapidly form a stronger clot and control severe bleeding. In vitro and rodent testing show clots that are tougher and may promote healing, with results indicating minimal immune reactivity and no organ toxicity. The method could form clots within 10–20 minutes and, when applied, stop bleeding in seconds, offering potential use in emergency care, wound management, and surgeries. However, further trials in larger animals and humans are needed before clinical deployment.
