Stopping bleeding, closing wounds, repairing organs—these are everyday challenges in medical and surgical practice. In the journal Angewandte Chemie, French researchers have now introduced a new method that employs gluing by aqueous nanoparticle solutions to effectively control bleeding and repair tissues. In animal tests, their approach proved easy to apply, rapid and efficient even in situations when conventional methods are traumatic or fail. Sutures and staples are efficient tools for use in surgery and treating wounds. However, the usefulness of these methods can be limited in inaccessible parts of the body or in minimally invasive surgeries. In addition, stitching damages soft tissues such as liver, spleen, kidney, or lung. A good adhesive could be a useful alternative. The problem is that the adhesion must take place in a wet environment and that the repaired area is immediately put under strain. Previous adhesive technologies have had problems, including insufficient strength, inflammation due to toxic substances, or complicated implementation because a chemical polymerization or cross-linking reaction must be carried out in a controlled manner.
