MUMBAI, India, Oct. 31 -- Intellectual Property India has published a patent application (202411028509 A) filed by Shoolini University Of Biotechnology And Management Sciences, Solan, Himachal Pradesh, on April 8, 2024, for 'green synthesis of fe3o4 nanoparticle with enhanced photocatalytic and antibacterial activities.'
Inventor(s) include Dr. Garima Rana; Dr. Pooja Dhiman; Dr. Amit Kumar; and Dr. Gaurav Sharma.
The application for the patent was published on Oct. 31, under issue no. 44/2025.
According to the abstract released by the Intellectual Property India: "The present invention discloses Fe3O4 nanoparticles for the degradation of organic pollutants, comprising 25-35 mg of cannabis sativa roots, 4-6 g of citric acid, and 4-6 g of iron nitrate. These nanoparticles exhibit the ability to degrade 99.55% of malachite green dye within 60 minutes. The Fe3O4 nanoparticles, manufactured using cannabis sativa roots, demonstrate potential for use as highly effective photocatalysts in the degradation of malachite green. Additionally, bacterial efficacy testing was conducted against bacterial strains including Escherichia coli, Salmonella typhi, Shigella sonnei, Pseudomonas aeruginosa, and Staphylococcus aureus. The efficacy of the CF2 nanoparticles remains mostly unaffected after each successive cycle. Upon the 5th reuse, the efficiency reaches a value of 75.24%."
