A multifunctional polyacrylonitri…kness wound healing.

Researchers created a wound dressing layered with chamomile extract and silver sulfadiazine that showed strong antibacterial effects against common bacteria and helped wounds close faster in animal studies. The dressing stayed intact under stress, broke down naturally in the body, and didn't harm skin cells. In vivo results showed it promoted skin regrowth and collagen production—basically, it helped damaged tissue rebuild itself.
