IUT researchers develop nano-suture

ISFAHAN, Oct. 18 (MNA) – Researchers in Isfahan University of Technology have developed a suture incorporating nanofibers in its fabric.

The laboratory-scale produced suture is biodegradable according to Fatemeh Haqiqat, PhD student of Textile Engineering and the major researcher of the nanoproduct. With recent advances in nanotechnology, production of nanofibers through twisted continuous nanofiber yarn by electrospinning process has been on the focus of research. Using biodegradable and bio-adaptable nanofibers to produce sutures has provided medicine with products such as drug delivery systems and biodegradable suture.
“Poly (lactic-co-glycolic acid) (PLGA) is the main fiber to produce nanosuture. It has successfully passed mechanical strength tests,” said Haqiqat, “different polymers could be used to produce nanosuture; however, in common production of suture, the raw material poses great restrictions on the producer.”
“Using anti-bacterial medicines and sutures capable of drug delivery becomes a reality through electrospinning,” said Haqiqat. “Synthetic absorbable suture in Iranian market are imported, and few producers would produce natural biodegradable sutures. Research indicates that natural biodegradable sutures are degraded rapidly compared to synthetic sutures,” said the researcher.
Haqiqat cited low permeability of the nanosuture as another advantage for the product. “It is a property of suture to show whether the infections of the wounds infiltrates to the suture; however, nanofiber fabric of the suture makes it poor in mechanical properties compared to other similar sutures,” she told Mehr News local correspondent.
The findings of the research have been published in Fibers and Polymers Journal in an article which she coauthored with Dr. Abdolkarim Hosseini, IUT lecturer.
