Iranian Scientist Create 'Smart' Bandages to Heal Chronic Wounds

An Iranian scientist has developed "smart" bandage that can precisely deliver different medications to the wound with independent dosing.

For the first time, faculty in the biomedical engineering department—a shared department with the UConn School of Dental Medicine, School of Medicine, and School of Engineering— designed a wirelessly-controlled, or "smart," bandage and corresponding smartphone-sized platform that can precisely deliver different medications to the wound with independent dosing, Phys.org reports.

Based on the report, Dr. Ali Tamayol, associate professor, and researchers from the University of Nebraska-Lincoln and Harvard Medical School could develop the “smart” bandage which is equipped with miniature needles that can be controlled wirelessly, allowing the drugs to be programmed by care providers without even visiting the patient.

"This is an important step in engineering advanced bandages that can facilitate the healing of hard to treat wounds. The bandage does not need to be changed continuously," says Tamayol.

The research, recently published in the Advanced Functional Materials journal, was first conducted on cells and later on diabetic mice with full thickness skin injury. With this technology, the mice showed signs of complete healing and lack of scar formation, showing the bandages' ability to significantly improve the rate and quality of wound healing in diabetic animals.

These findings can potentially replace existing wound care systems and significantly reduce the morbidity of chronic wounds—which will change the way diabetic wounds are treated.
