In a groundbreaking development, scientists from Waseda University and the Japanese National Defense Medical College have created a revolutionary "nano-film" designed for surgical use. This ultra-thin material measures just 75 nanometers in thickness—equivalent to one thousandth of cellophane. The film is biodegradable, meaning it can naturally dissolve within the body after serving its purpose. Researchers claim this is the thinnest medical tape ever developed, offering a new alternative for wound repair.
Traditionally, surgeons rely on sutures or staples to close wounds, and sometimes they use fibrin-based medical films. While fibrin helps in clotting blood and bonding to wounds, it often leads to unwanted adhesions with surrounding tissues. The newly developed transparent, viscous film, however, is made from a compound derived from crab shells and seaweed gel. It's highly flexible and can stick to organs without the need for additional adhesives, significantly reducing the risk of tissue adhesion.
In experiments conducted on dogs, the nano-film was applied to a 6 cm wound around the lungs. After a month, the wound showed excellent healing results. The research team is now planning to begin clinical trials in three years, aiming to bring this innovative technology to human patients. The potential impact on surgery could be enormous, offering a safer and more effective way to treat wounds while minimizing complications.
