MUMBAI, India, Aug. 12 -- Intellectual Property India has published a patent application (202421072371 A) filed by Amity University Madhya Pradesh on September 25, 2024, for A Novel Protein-Polymer-Nanocomposite (ppnc)-Based Sensor For Detection Of Toxic Gases And Method Thereof.
Inventors include Pankaj Kumar Mishra; Neeraj Kumar Gaur; and Harish Kumar Sharma.
The application for the patent was published on August 07, 2026, under issue no. 32/2026.
Abstract: The invention presents a novel protein-polymer-nanocomposite (PPNC) based sensor designed for detecting toxic gases. This sensor leverages the unique properties of hemoproteins, such as hemoglobin, immobilized within a conductive polymer matrix, specifically polyaniline (PANI), enhanced with zinc oxide (ZnO) nanoparticles. The resulting PPNC composite offers superior sensitivity and selectivity for various toxic gases, including carbon monoxide (CO), ammonia (NH3), hydrogen sulfide (H2S), and nitric oxide (NO). The sensor operates by detecting changes in electrical conductivity or electrochemical signals caused by the binding of toxic gases to hemoglobin. The PPNC-based sensor is cost-effective, easy to fabricate, and environmentally friendly, making it suitable for applications in environmental monitoring, workplace safety, healthcare, and more.
