MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202641018731 A) filed by Ms. Nalina R, Shivamogga, Karnataka, on Feb. 19, for 'phytoaccumulation-assisted synthesis of zno nanoparticles from thermal conversion of zinc-enriched calotropis gigantea biomass.'
Inventor(s) include Ms. Nalina R; Dr. G Nagaraju; Ms. Gagana G R; and Dr. Latha K P.
The application for the patent was published on Feb. 27, under issue no. 09/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a green and sustainable method for synthesizing Zinc Oxide (ZnO) nanoparticles using zinc-enriched Calotropis gigantea biomass. Due to the inherent zinc deficiency in natural soils, the growth medium is supplemented with 1 M Zinc Nitrate to facilitate effective phytoaccumulation within the plant tissues. The plant acts as a biological vehicle, sequestering and distributing zinc ions throughout its organic matrix. The harvested biomass is washed, dried, and subjected to controlled calcination at 500 C, converting the bio-bound zinc into crystalline ZnO nanoparticles. This method eliminates the need for hazardous synthetic precursors and external stabilizers, utilizing the plant's internal structure as a natural template. The resulting nanoparticles exhibit a characteristic hexagonal wurtzite phase, as confirmed by Powder X-ray Diffraction (PXRD). The process is scalable and eco-friendly, offering high-potential materials for applications in photocatalysis, antimicrobial activity, and environmental remediation while valorizing renewable biomass."
