Iranian researcher invents low-cost, low-risk nano-dressing for wounds

An Iranian researcher has managed to make nano-wound dressings with herbal compounds at a low cost and with antibacterial properties.

Iran’s Mehr news agency quoted Vice President’s Office for Science, Technology and Knowledge-based Economy as saying that Sepideh Hazari, a PhD graduate in applied chemistry from Tabriz University has achieved the remarkable success, adding the wound dressing produced in the research can be used for different types of wounds.

Hazari said, “Many efforts have been made to use new treatment methods that can help speed up the wound healing process, prevent wound infection, increase the tensile strength of the wounded area, reduce scar tissue at the wound site, and prevent the patient from becoming disabled.”

The researcher further said, “Traditional wound coverings, including wool, cotton, natural and synthetic bandages and gauze, are used as primary or secondary dressings. Usually, they are dry wound dressings and cause moisture evaporation and dehydration of the wounded area, which in turn makes the wound more sticky and painful.”

Hazari said the new dressings create sufficient moisture in the wound by using different materials, including hydrogels, which are polymeric tissues that have the ability to swell in water and retain moisture in their structure without dissolving in it.
