Gizmos & Gadgets: New Nano-embedded Bandage Can Heal Wounds Faster

September 30, 2016 – Researchers at Zewail City of Science and Technology in Egypt have developed a bandage for treating wounds that promotes healing faster than traditional coverings. The bandage contains the anti-epilepsy drug Phenytoin encapsulated in nanoparticles carried on nanofibers. States Ibrahim El-Sherbiny, Director, Center for Materials Science, the bandage allows “a well-controlled release of phenytoin, distributing it effectively.”

A single bandage can help heal a wound within 10 days.

How does it work?

The embedding of the drug in nanoparticles allows for a low percentage timed release which makes it easily absorbed by the bloodstream without undesirable side affects. Based on the size of the bandage it can distribute the drug over an entire area that is infected and thus promote healing.

The bandage has been tested in the laboratory on human tissue as well as mice. Results show complete healing as the bandage promotes cell regrowth as well as collagen, an important skin protein. The bandage also minimizes scarring.

Results of the research appear in the May edition of the Journal of Applied Materials & Interfaces.

The Zewail team is currently working on development of a specialty bandage for diabetics since patients suffering from this condition are very slow to heal.
