Iran-Made Nano-Based Wound Dressings Treat Burns, Chronic, Acute Bed Sores

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 recently 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.

“The dressing does not cause infection either. In this dressing, we have used a series of nanoparticles and peptides that have been produced in the form of nanofibers and they provide a substrate for red blood cells and platelets to attach to and easily cause blood to clot and prevent bleeding,” he added.

Mehdizadeh said that the nanoparticles used in the product are gold nanoparticles and a special peptide produced in the laboratory, adding that these types of dressings can be applied in open heart surgery, bone, skull, jaw and face surgeries.

In another development, a knowledge-based company in Iran succeeded in production of home-made blood coagulants that stop bleeding in the shortest possible time and with the least amount of tissue destruction.

‘Hilda’ blood clotting powder, produced with modern methods, uses biological and safe polymers to prevent blood loss in a short period of time. The biodegradable and biocompatible composition is completely absorbed by the body enzymes after use. This polysaccharide reduces the need for blood transfusion by quickly stopping all types of bleeding (capillary, venous and arterial).
