A team of engineers and scientists from the RMIT University, Melbourne, Australia, have reportedly developed a smart wound dressings with inbuilt nanosensors integrated that possess the ability to glow to notify patients when their wound is not properly healing.
According to reports, the smart wound dressings harness the strong antifungal and antibacterial properties of magnesium hydroxide. Additionally, wound dressings incorporate fluorescent sensors that flash brightly when exposed to UV light if the wound starts to get infected. This allows the dressing to be used as an effective tool to track the healing process.
The dressings are less expensive to manufacture than silver-based dressings. Yet, they are just as efficient at combating fungi and bacteria, with an antimicrobial potency that can last up to a week.
Dr. Vi Khanh Truong, who led the research project, stated that the innovation of low-priced antimicrobial dressings integrated with healing sensors would be a big advancement in wound treatment.
So far, the only approach to monitor wound development is by removing the dressing, which is both unpleasant and dangerous since it gives pathogens an opportunity to attack. The Smart dressings not only combat germs and decrease inflammation to support healing, but they also feature luminous sensors that detect and track infection, Dr. Truong added.
The nanosheets of magnesium hydroxide react to pH level changes, making them perfect for use as healing sensors. Healthy skin is somewhat acidic by nature, whereas infected wounds are slightly alkaline.
These nanosheets shine brightly in alkaline settings and fade under acidic conditions when exposed to UV light. Through this the dressing highlights the varied pH values that correspond to different stages of wound healing.
According to Dr. Truong, the fluorescent nanosheet making process was relatively easy to scale up for widescale manufacturing.
The global advanced wound dressing industry is now worth US$6.9 billion and is anticipated to reach US$9.9 billion by 2028. This growth is directly attributed to the technical advancements, an increase in surgical operations, as well as an increase in the incidence of chronic wounds and chronic illnesses like diabetes and cancer.
