Researchers at the RMIT came up with a drastic invention. The new smart wound dressings are composed of built-in healing sensors. Isn’t that amazing? Moreover, the nanosensors glow and notify the patients of the progress of wound healing. This wound dressing invention has opened up doors to easier wound healing procedures.
Mechanism of wound dressing invention
Researchers at the RMIT University in Melbourne, Australia, emerged with a superb idea of wound dressing. They became successful in utilizing the anti-bacterial and anti-fungal properties of Magnesium Hydroxide. Researches tell that magnesium is highly antibacterial, antifungal and biocompatible when it comes to medical usage.
Dr. Vi Khanh Truong led this project. Further, he explained the significant advancement would decrease the rate of pathogenic attacks. As previously, changing the bandages made the wounds prone to bacterial attacks. Whereas smart wound dressing invention will promote wound healing and identify with the healing mechanism progress.
Author, Dr Adam Truskewycz led the study, published in ACS Applied Materials and Interfaces. He was the pioneer in wound dressing development as he prepared the nanosheets of fluorescent magnesium hydroxide. They actually contour to the curves of bandage fibres.
They prepared the nanosheets which are 10-100 thousand times thinner than a human hair. Afterwards, they embedded the nanosheets onto nanofibres. The changes in pH respond to the senses of healing. Normally skin has a low pH i-e: acidic. However, the wounded skin has a pH higher than 7 hence, it is alkaline.
The laboratory bandage tests show that they are totally fine for humans as they destroy several pathogens such as Candida auris. When the wound does not heal properly, the fluorescent sensors of multifunctional dressings glow under the ultraviolet radiations.
Limit and affordability
The recent advanced wound healing market values currently at an estimate of $US6.9 Billion. However, the market is awaited to grow $US9.9 billion till 2028.
“Normally, antimicrobial wound dressings start to lose their performance after a few days but our studies show these new dressings could last up to seven days,”
