Iran’s Royan Institute Produces Biological Wound Dressing for Diabetic Patients

“One of our most important achievements this year has been the production of two types of medical skin, including single-layer skin and double-layer skin,” said Parvaneh Afsharian.

“The first product is a single-layer skin designed to treat third-degree burns and is used in cases where the body does not have any healthy skin for transplantation,” she explained, adding that this product has dimensions larger than a layer of human skin cells.

“The second product, a double-layer skin consisting of keratinocytes and fibroblasts, is designed to treat deep chronic wounds and is known as a completely biological wound dressing,” Afsharian said.

The clinical trials of this product were also conducted last year and has now been added to the country's list of medicines, she added.

In a relevant development in January 2023, several Iranian companies presented their nanotechnology-based products to the market to treat chronic burns, acute diabetic ulcers, acute bedsores and chronic wounds.

One of the nano-based products of these companies is antibacterial dressing bandage which was mass-produced in 2001 and it contains silver nanoparticles with antibacterial properties.

Due to the strong antibacterial properties of silver nanoparticles, this bandage is used to control infection in burns and wounds as it leaves its antimicrobial and anti-inflammatory effects with the slow release of silver ions.

The antibacterial bandage is used in the treatment of acute burns, diabetic wounds, bedsores and chronic wounds.

Another nano-based product of the Iranian companies is blood and water absorbent pad which contains nano dendrimers.

The pad was produced in 2001 to accelerate wound healing, prevent infection and bleeding, maintain wound moisture, and protect the affected area from mechanical damages, including shock or scratch.

The pad is used along with washing liquids, disinfectants, bandages, cotton and sterile gauze.

Another product produced by the Iranian researchers at a technological company is a dressing capable of preventing bleeding in bone, jaw and face surgery within 30 seconds.

“The dressing we have produced can reduce bleeding in bone surgery by 90% in nearly 20 to 30 seconds,” said Keyhan Mehdizadeh, one of the researchers of the project.
