Researchers at the Technion-Israel Institute of Technology have developed a strong, flexible bio-material that may be used someday to close wounds with minimal scarring and rejection by the immune system. Spun from a common blood protein, the material could be used to make the thin threads needed for wound sutures, larger dressings for wounds, and other anti-adhesion membranes used in abdominal surgery, according to Technion researchers Eyal Zussman, Arie Admon, and their colleagues.
The scientists turned the globular protein bovine serum albumin into thick mats using electrospinning, a technique that uses an electrical charge to pull and stretch liquid droplets into nano-sized fibers. Though many researchers have used the technique to spin fibers from organic materials, it has been a challenge to spin organic materials into stable threads, making it necessary to spin a blend of artificial and natural molecules.
Since it is made entirely from biological material, with no synthetic additives, the material is more likely to integrate with the body's natural tissues and leave less of a scar, which could make it ideal for wound closure after Caesarean surgery or cosmetic procedures, said Zussman.
