Revolutionary Smart Wound Dressing Developed by NIT Raurkela Researchers

Innovative Wound Care Solution

Raurkela: A team of researchers from the National Institute of Technology, Raurkela (NITR) has introduced an advanced smart wound dressing that alleviates pain during dressing changes, minimizes infection risks, and accelerates healing. This innovative solution serves as a cost-effective alternative to traditional cotton gauze. The project, spearheaded by Prof. Prasoon Kumar, an assistant professor in the Department of Biotechnology and Medical Engineering, tackles a significant drawback of standard cotton gauze, which tends to stick to wounds, potentially harming newly formed tissue upon removal and heightening infection risks.

The smart dressing integrates chitosan-coated cotton gauze with a nanofibrous layer created through electrospinning, infused with curcumin, a natural antimicrobial agent. This layer is strategically placed between the wound and the gauze, reducing direct contact and making dressing changes less painful while safeguarding newly formed tissue. Additionally, the nanofibrous layer ensures a sustained release of curcumin, which helps maintain a sterile wound environment, inhibits bacterial growth, and fosters tissue regeneration. Prof. Kumar noted, “Our laboratory experiments demonstrated that this dressing significantly lessens wound adhesion compared to traditional cotton gauze. The continuous release of curcumin offers antibacterial protection, while the nanofibrous layer promotes cellular growth and tissue healing.”

Designed with straightforward, scalable, and economical fabrication techniques, the smart dressing is projected to cost between INR 50-60 for a 10 cm × 4 m size, compared to approximately INR 30 for conventional cotton gauze. The research findings have been published in Emergent Materials, and the team is looking to patent their technology while seeking partnerships with industry players to initiate clinical trials and facilitate commercialization.
