MUMBAI, India, Jan. 2 -- Intellectual Property India has published a patent application (202541122894 A) filed by Dr. M. G. R. Educational & Research Institute, Chennai, Tamil Nadu, on Dec. 5, 2025, for 'green biosynthesis of silver nanoparticles using manilkara zapota flower extract.'
Inventor(s) include Sindhu Govindaraj; Gnanamurthy Kumaran; and Gomathi Kannayiram.
The application for the patent was published on Jan. 2, under issue no. 01/2026.
According to the abstract released by the Intellectual Property India: "A green, phytochemical-mediated method for synthesizing silver nanoparticles using an aqueous extract of Manilkara zapota (sapota) flower material. The process employs naturally occurring flavonoids, tannins, polyphenols, and associated metabolites within the flower extract to act simultaneously as reducing, stabilizing, and capping agents, enabling the conversion of silver ions into nanoscale metallic silver under mild reaction conditions without toxic chemicals. The method includes controlled preparation of the flower extract, biogenic reduction of silver ions, monitoring of surface plasmon resonance-based colorimetric transitions, and purification of nanoparticles through centrifugation and washing cycles. The resulting silver nanoparticles exhibit stable crystalline structure, uniform morphology, antioxidant activity, antimicrobial efficacy, and high cytocompatibility, making them suitable for biomedical, cosmetic, environmental, agricultural, and pharmaceutical applications. The invention establishes a sustainable, cost-efficient, and scalable platform for producing functional silver nanomaterials through a fully eco-friendly biosynthesis route."
