Stitches may soon become obsolete. Paris researchers have developed an aqueous nanoparticle solution that closes wounds in 30 seconds, even in liver, spleen and lung.

Innovative strategy to facilitate organ repair

This easy-to-use gluing method has been tested on rats. When applied to skin, it closes deep wounds in a few seconds and provides a esthetic, high quality healing. It has also been shown to successfully repair organs that are difficult to suture, such as the liver. Finally, this solution has made it possible to attach a medical device to a beating heart, demonstrating the method's potential for delivering drugs and strengthening tissues.

... nanoparticles contained in a solution spread out on surfaces to be glued bind to the gel's (or tissue's) molecular network. This phenomenon is called adsorption. At the same time the gel (or tissue) binds the particles together. Accordingly, myriad connections form between the two surfaces. This adhesion process, which involves no chemical reaction, only takes a few seconds. In their latest, newly published study, the researchers used experiments performed on rats to show that this method, applied in vivo , has the potential to revolutionize clinical practice.

Can you imagine, Jim. They used to stitch up patients like pieces of cloth.
