MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202511115510 A) filed by Nims University, Jaipur, Rajasthan, on Nov. 22, 2025, for 'biogenic production of antimicrobial magnesium oxide nanoparticles.'
Inventor(s) include Shruti Prabha Patel; and Rashmi Vats.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "A green synthesis method (100) for the production of magnesium oxide (MgO) nanoparticles with effective antimicrobial activity. The method (100) involves the preparation of a phytochemical-rich aqueous extract (101) from Brassica nigra leaves and/or stems, combining the extract (101) with a magnesium precursor to create a reaction mixture (102), heating the mixture at approximately 90 C with stirring, and the slow addition of a base solution (103) to precipitate magnesium hydroxide. The following purification by centrifugation and ethanol washing gives rise to MgO nanoparticles with phytochemical coatings. The resultant MgO nano antibiotic (200) consists of biomolecule-coated nanoparticles as reducing as well as capping agents, including polyphenols, flavonoids, and proteins. Such nanoparticles display uniform size distribution, high surface area, and broad-spectrum antimicrobial activity against Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa."
