Iranians produce coatings for third-degree burns

January 31, 2014

Iranian researchers from Amir Kabir University of Technology, in association with colleagues from Iran Medical University and Tehran Heart Center, have succeeded in the production of antimicrobial nanofibrous coatings with the ability of absorbing pus and infectious materials.

The nanofibrous coating is made of chitosan and polycaprolactone polymers, and has a good performance in the treatment of skin injuries such as deep wounds and third-degree burns, Fars News Agency reported.

It also has applications in medical and pharmaceutical industries, especially in centers treating burn injuries.

One of the most important issues in the first hours after burning is to control and take out infection, and to prevent the entry of microbes and bacteria into the wound.

Therefore, the main objective of this research was to produce biocompatible and antibacterial scaffolds from chitosan biological polymer and the artificial and biocompatible polymer of polycaprolactone in the form of porous nanofibrous coatings with high ability to take out all liquids flowing from the burnt or wounded area.

The polymer would help treat various types of deep wounds and third-degree burns.

The researchers used a mixture of biocompatible artificial polymers of polycaprolactone, chitosan natural polymer and polyvinyl alcohol artificial polymer. They produced the nanofibrous coating after the preparation of the solution through electrospinning method so they can be used in the form of a cell-free scaffold with stem cell.

Pathological studies showed the scaffold's effectiveness in comparison with the control group. The conservation of nanometric physical structure during the treatment results in the sorption of more fibroblast into the derma layer, and the more possibility of collagen making leads to the better treatment of the skin.
