Scientists develop light activated nanotech to treat chronic wounds
Scientists have come up with a cool new way to treat chronic wounds, like diabetic ulcers and burns, which don't respond to antibiotics.
Their light-activated nanotechnology breaks down tough bacterial biofilms, which normally protect bacteria and make healing slow.
This could mean faster recovery for people dealing with these hard-to-treat injuries.
Tests destroyed over 95% of bacteria
In animal tests, a gel combining lysozyme (an antibacterial protein) and light-sensitive materials wiped out more than 95% of bacteria.
Another method using gold nanoparticles and graphene oxide quantum dots destroyed 97% of bacteria in laboratory tests and healed nearly 99% of wounds in animals.
The technology even reduced bacteria around implanted materials in animal studies.
Human safety studies remain necessary before hospitals can adopt these therapies, but this research might be a big step forward for wound care.
