MUMBAI, India, June 24 -- Intellectual Property India has published a patent application (202411093049 A) filed by University Of Lucknow on November 28, 2024, for A Method For Synthesizing Copper Oxide Nanoparticles (cuo Nps), And Its Application In Paper Sensor For Detection Of Heavy Metal Ions.
Inventors include Roli Verma; and Akanksha Mishra.
The application for the patent was published on June 12, 2026, under issue no. 24/2026.
Abstract: The present invention relates to a method for synthesizing Copper Oxide Nanoparticles (CuO NPs), by avoiding the use of harmful chemicals and its application in making paper sensor for detection of heavy metal ions. Thus the leaf extract of Ocimum sanctum can be effectively utilized for the bio-reduction of CuSO4 to synthesize CuO nanoparticles (CuO NPs) in a one-step process. The EDX spectrum further confirms the presence of copper in the form of oxide. The green method can be applied for a rapid, easy, and eco-friendly synthesis of copper oxide NPs. These nanoparticles are useful for the detection of Pb2+ and Fe3+ ions selectively by changing the probe color. The detection is indicated by a color change in the probe, from brown to colorless for Pb²? ions and to an intense yellow for Fe³? ions, respectively. The synthesized CuO NPs works in acidic medium i.e. at pH 4.2 rather than basic.
