MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202541124035 A) filed by Saveetha Institute Of Medical And Technical Sciences, Chennai, Tamil Nadu, on Dec. 9, 2025, for 'a novel formulation consisting of green synthesized calcium oxide and tannic acid incorporated wound healing nanogel.'
Inventor(s) include Dr. A. Kanchana Mala; Dr. S. Rajesh Kumar; Dr. Syed Shehnaz Ilyas; and Deepak Nallaswamy Veeraiyan.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "This invention introduces a green-synthesized nanogel that combines calcium oxide nanoparticles, Achyranthes aspera extract, and tannic acid for enhanced wound healing. The nanogel leverages calcium oxide nanoparticles produced through an eco-friendly synthesis method using Achyranthes aspera, known for its medicinal properties. These nanoparticles stimulate cellular regeneration and tissue repair, while tannic acid, a natural polyphenol, provides antimicrobial, antioxidant, and anti-inflammatory benefits. Together, these components create an optimal environment for wound healing, reducing infection risks and promoting faster tissue recovery. The nanogel forms a conforming layer over the wound site, which maintains moisture, absorbs exudate, and facilitates localized delivery of therapeutic agents, accelerating the natural healing process. Preclinical studies on this formulation have demonstrated a decrease in wound area, minimized scarring, and a reduction in bacterial load, making it a promising candidate for clinical applications, particularly in chronic wound management. The biocompatible, biodegradable nature of this nanogel makes it a sustainable alternative in advanced wound care, addressing the need for effective and eco-friendly therapeutic options."
