Iran-Made Two-Layer Wound Dressing Reduces Infection by 50 Percent
“Silk fibroin nanofibers, with a structure similar to the body's extracellular matrix, promote cell growth and increase the strength of damaged tissue. The hydrogel is a combination of alginate, gelatin, polydopamine, and zinc ions, which is made by 3D printing and provides antiseptic properties and faster wound healing,” Mana Haji Mohammad Hossein Kashi, a graduate of Amirkabir University of Technology and a senior researcher of this project, told ANA.
Noting that the wound dressing has received approval from the US Food and Drug Administration (FDA) for similar products due to the use of natural and body-compatible materials, she said, “Silk fibroin is extracted from cocoon production factories in Iran and alginate is extracted from algae in the Sea of Oman (Chabahar region in Southeastern Iran).”
“This not only reduces production costs by 40%, but also positions Iran as a regional pioneer in tissue engineering technology,” Haji Mohammad Hossein Kashi said.
“In addition to treating diabetic wounds and burns, this dressing can be used in skin graft surgeries and inflammatory diseases,” she underlined.
In a relevant development in November, Iranian researchers at a knowledge-based company had also succeeded in using nanotechnology to produce a special spray that treats wounds and skin infections.
“In our company, we have succeeded in producing a spray with a type of tree gum. Silver nanoparticles are used in this spray to accelerate the speed of wound healing,” Mehdi Qahreman Termeh, the managing director of the knowledge-based company, told ANA.
Noting that a certain amount of silver nanoparticles is used in the spray which does not penetrate the body and can heal the wound, he said, “The silver nano particles that we used in the wound healing spray have been approved by Iran Nanotechnology Innovation Council and are being produced and supplied to pharmacies.”
“Also, this nano spray accelerates the process of wound healing and the formation of new tissue, and removes pus and infection from the wound. Our product can be used to disinfect bedsores, diabetes, oral thrush, sore throat and uterine infections,” Qahreman Termeh said.
