Biological glue gun for wound healing

Glue stick to harden the mouth to reduce the risk of infection, heal, reduce scarring.

Inspired by hot glue guns, decorations, and toys . researchers at the Technionot Institute of Technology, Israel, develop into a hot glue gun that adheres to human tissues when being serious injuries.

According to Professor Boaz Mizrahi, head of the Biological Materials Laboratory, most serious injuries treated with pins and stitches have many drawbacks. The patient may suffer from pain, scarring of the scar, suture skills that require high skill from the doctor and sometimes removal after the tissue heals cause aesthetics.

The bio-gluing method can reduce the risk of stitches, avoid infection, less pain, improve the aesthetic effect after treating the wound. The patient does not need to spend time going to the medical facility to remove the thread but just wait for the mouth to heal itself and spontaneously flake.

Alona Shagan, a graduate student at the institute, said that unlike conventional glue guns, the gun warms glue at moderate temperatures right above the body so as not to cause burns. After that, it quickly hardens and decomposes within a few weeks. This adhesive is also suitable for adhesion of internal body tissues and is 4 times stronger than existing binders used for this purpose.

"Strong bonding with two edges of the wound. Molecular weight change allows control of adhesion strength, melting point and elastic properties. Tests on cells and laboratory animals, glue proved effective and non-toxic , " said Mizrahi.
