New Bandage Biodegrades When Wound Heals

A new fiber that releases antibiotics then biodegrades being used in new bandages…

Since the beginning of medical practices, bandages have served a very useful purpose, but that doesn’t mean they are perfect. Aside from the fact that persistent wounds can still become infected if they aren’t replaced often enough, there countless tons of biohazardous waste being produced each year as more and more tainted bandages are thrown in the trash.

Fortunately, researchers at the Tel Aviv University think they may have found a clean solution to rectify both of these problems. They have created fibers that release antibiotics at a controlled pace, then biodegrade after the wound has healed.

Professor Meital Zilberman, the researcher who pioneered the breakthrough fibers, said:

“We’ve developed the first wound dressing that both releases antibiotic drugs and biodegrades in a controlled manner…

“It solves current mechanical and physical limitations in wound-dressing techniques.”

The technology of the new wound dressing is extremely complicated as the bandages must maintain a controlled level of moisture, enable fluids from the wound to leave the infected tissue, all whilst providing protection from further infection.

That delicate balance is something Zilberman’s new fibers seem to strike with perfection. They combine positive mechanical and physical properties with what medical researchers call “a desired release profile of antibiotics.” In fact, research has already shown that after only two days, this dressing can eradicate infection-causing bacteria from serious wounds.

Researchers hope the new bandages will provide a more effective method of treatment for burn victims, since approx 70 percent of ll people with serve burns die from related infections. And because the bandages biodegrade instantly after the wound has healed, they leave little to no waste.

Although the new bandages aren’t quite ready for hospital use, they have already passed physical and mechanical tests. And Prof. Zilberman is currently seeking a strategic partner to develop the research so it can be taken to the commercial stage.
