Researchers develop smart wound dressings with built-in healing sensors
Researchers have developed smart wound dressings with built-in nanosensors that glow to alert patients when a wound is not healing properly.
The multifunctional, antimicrobial dressings feature fluorescent sensors that glow brightly under UV light if infection starts to set in and can be used to monitor healing progress.
The smart dressings, developed by a team of scientists and engineers at RMIT University in Melbourne, Australia, harness the powerful antibacterial and antifungal properties of magnesium hydroxide.
They are cheaper to produce than silver-based dressings but equally as effective in fighting bacteria and fungi, with their antimicrobial power lasting up to a week.

New Superbug-Destroying Coating Could Prevent and Treat Deadly Infections

A new superbug-destroying coating developed by scientists could be utilized on implants and wound dressings to inhibit and treat potentially lethal fungal and bacterial infections.

The material is considered as one of the thinnest antimicrobial coatings created so far and is powerful against an extensive range of drug-resistant fungal and bacterial cells but harmless against human cells.
Antibiotic resistance is considered a significant universal health threat, resulting in a minimum of 700,000 deaths annually. The lack of development of new antibacterial therapies could increase the death toll to 10 million people annually by 2050, which relates to $US100 trillion in health care charges.
