MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202541045233 A) filed by Vinayaka Missions Reasearch Foundation- DU; and Dr. K. Indra Priyadharshini, Salem, Tamil Nadu, on May 10, 2025, for 'eco-friendly synthesis of iron, zinc nanoparticles using calotropis extract for biomedical and catalytic applications.'
Inventor(s) include Dr. K. Indra Priyadharshini; Dr. L. Chitra; and Dr. S. Penislusshiyan.
The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "The invention discloses a controlled aqueous synthesis process wherein Calotropis procera leaf extract reduces Fe? and Zn? ions under alkaline conditions (pH 10). The phytochemicals present in the extract function simultaneously as reducing, chelating, and capping agents. Under identical botanical conditions, iron forms predominantly amorphous nanoparticles, while zinc forms crystalline ZnO nanoparticles. In the mixed precursor system, iron disrupts zinc lattice development, resulting in disordered Fe-Zn nanostructures. The process eliminates toxic reagents, requires moderate temperature (60-70 C), and yields stable phytochemical-capped nanoparticles suitable for biomedical and catalytic applications."
