MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202541133461 A) filed by Rajalakshmi Engineering College, Chennai, Tamil Nadu, on Dec. 30, 2025, for 'a green process for fabricating a naturally conductive hydrogel incorporating bioactive plant and al.'
Inventor(s) include Dr. S. Sudha; and S. Abiramy.
The application for the patent was published on Feb. 27, under issue no. 09/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a green and sustainable process for the preparation of a bioactive, electrically conductive hydrogel intended for biomedical applications. The process involves the aqueous extraction of bioactive compounds from Mimosa pudica and Spirulina platensis using 280 controlled thermal extraction conditions. A polymeric matrix is prepared by dissolving polyvinyl alcohol (PVA) and sodium alginate (SA) separately in distilled water, followed by blending the polymer solutions in a defined volume ratio to form a homogeneous polymer mixture.The plantbased extracts are incorporated into the polymer matrix to form a uniform hydrogel precursor, which is subsequently subjected to repeated freeze-thaw cycles to achieve physical crosslinking 285 without chemical crosslinkers. The resulting hydrogel exhibits intrinsic electrical conductivity, bioactivity, porosity, and mechanical stability, providing a sustainable method for producing multifunctional hydrogels suitable for biomedical uses such as supporting cellular interactions, antibacterial activity, and tissue regeneration."
