Current surgical adhesives are quite toxic, have limited bonding power, and do not work well in areas that are too wet, such as heart tissue, according to Pannochka, an online publication for girls and women aged 14 to 35.. net Inspired by the biology of worms, researchers at Brigham Women's Hospital, led by Dr. Jeffrey Karp, were able to overcome these limitations..

In Science Translational Medicine, they report on the development and testing of a hydrophobic light-activated adhesive (HLAA).

This adhesive is flexible, elastic, performs well in humid environments and does not change properties when in contact with blood.. The substance only needs to be applied to the bonding area and exposed to UV rays for a few seconds..

In tests on rats, HLAA has been successfully used to seal defects in the heart wall, according to Boston scientists..

In pigs, patches that were applied to the ventricular septum of a beating heart and treated with ultraviolet light remained in place even after a significant increase in pressure with injections of adrenaline..

The main components of HLAA are glycerol and sebacic acid, substances that exist in our body and are easily metabolized..

The new technology is licensed by a European company that hopes to bring it to market within 2-3 years.
