MUMBAI, India, July 7 -- Intellectual Property India has published a patent application (202641060170 A) filed by Nivetha S; Madhumitha S; and Hemalatha Venkatesan on May 12, 2026, for Fabrication Of Sulfated Polysaccharide Infused Hydrogel Wound Dressings From Marine Macroalgae.
Inventors include Nivetha S; Madhumitha S; and Hemalatha Venkatesan.
The application for the patent was published on July 03, 2026, under issue no. 27/2026.
Abstract: The present invention relates to a bioactive multilayer hydrogel wound dressing enriched with sulphated polysaccharide-rich algae extract for improved wound healing and tissue regeneration applications. The developed dressing is designed to provide a moist, protective, and bioactive environment suitable for effective wound management. The multilayer structure comprises a bottom hydrogel layer responsible for moisture retention and exudate absorption, a middle medicated gauze layer loaded with algae-derived bioactive compounds, and a top protective layer that provides mechanical stability and protection against external contamination. The algae extract incorporated into the dressing contains sulphated polysaccharides along with naturally occurring antioxidant, antimicrobial, and anti-inflammatory compounds that enhance cellular proliferation, reduce microbial infection, minimize oxidative stress, and accelerate the wound healing process. The hydrogel matrix possesses high water absorption capacity, good swelling behavior, biocompatibility, flexibility, and controlled release properties, thereby ensuring sustained delivery of therapeutic compounds to the wound site. The fabricated hydrogel dressing can be prepared using biocompatible polymeric materials through a layer-by-layer assembly technique and is suitable for application in acute and chronic wounds, including diabetic ulcers, burns, surgical wounds, cuts, and pressure sores. The invention provides an eco-friendly and effective alternative to conventional wound dressings by integrating natural marine-derived bioactive compounds with hydrogel-based wound care technology. The developed dressing improves healing efficiency, maintains moisture balance, enhances patient comfort, and reduces the risk of secondary infection and delayed wound healing.
