MUMBAI, India, June 16 -- Intellectual Property India has published a patent application (202611054946 A) filed by Netaji Subhas University Of Technology, New Delhi, on April 30, for 'green synthesis of tio2 nanoparticles using tridax daisy.'
Inventor(s) include Anne Masih; Samiksha Dabas; Manish Kumar; and Om Prakash Thakur.
The application for the patent was published on June 5, under issue no. 23/2026.
According to the abstract released by the Intellectual Property India: "The invention discloses a sustainable, buffer-free green process for the synthesis of high-purity, bio-capped titanium dioxide (TiO2) nanoparticles using an aqueous leaf extract of Tridax procumbens (Tridax daisy) and Titanium Isopropoxide (TTIP). The process utilizes the phytochemical richness of the Tridax extract, specifically flavonoids, alkaloids, and tannins, to serve as a dual-functioning reducing and stabilizing agent. By employing TTIP as the sole metal precursor in a buffer-free medium, the invention eliminates the production of corrosive halide fumes and prevents sodium/chloride (Na+/Cl -) ionic contamination, achieving biomedical-grade purity. The synthesis is conducted under ambient atmospheric pressure and low-temperature conditions, transforming an invasive weed into high-value nanomaterial. The resulting nanoparticles are homogeneous and stable, suitable for applications in photocatalysis, antimicrobial coatings, and environmental remediation."
