According to the abstract released by the Intellectual Property India: "The present invention relates to a marine collagen-red algal hybrid wound-healing patch designed for the therapeutic management of diabetic foot ulcers (DFUs) in elderly patients. The patch integrates marine collagen, which provides a porous scaffold for cellular proliferation and tissue regeneration, with red algal bioactive components that exhibit antimicrobial, antioxidant, and anti-infhimmatory properties. This synergistic combination promotes accelerated wound healing by enhancing angiogenesis, reducing microbial colonization, and maintaining optimal wound moisture. The hybrid patch is fabricated as a flexible, biocompatible . dressing .that adheres to the ulcer surface, ensuring sustained bioactive delivery and improved healing outcomes compared to conventional dressings. The invention offers a cost-effective, safe, and non-invasive solution for the treatment of DFUs, thereby reducing complications, recurrence, and risk of amputation in elderly diabetic populations."
