Australian researchers have developed a new type of smart wound dressing that can detect infection and improves healing.
The new technique involves using silk woven with nano-diamonds to treat injuries like burns, skin grafts and chronic wounds.
Researchers at RMIT University said the smart dressings effectively sensed wound temperature, which is an early sign of infection, promoted healing and reduced infection from certain bacteria.
As a non-invasive measurement of wound temperature, this new technology provides an accurate way to monitor wound quality, compared to the very subjective method of visual assessment.
The study shows the smart membranes can detect early signs of infection and protect wounds while also maintaining the flow of oxygen and nutrients to the area.
Senior researcher Professor Brant Gibson said it offered a solution to the global challenge of wound care and healing.
“Traditional wound management presents a significant challenge for clinicians, who have to regularly check for infection by looking for signs of redness, heat and swelling,” Professor Gibson said.
“However, once these visual signs appear, inflammation and infection are far advanced, making therapies or interventions substantially more challenging.
“This new technology would aid clinicians to detect infections earlier and non-invasively without the painful procedure of dressing removal,” he said.
