MUMBAI, India, May 30 -- Intellectual Property India has published a patent application (202311081010 A) filed by Amity University, Noida, Uttar Pradesh, on Nov. 29, 2023, for 'n-p junction-based chemiresistive sensor provided with nano graphite platelets and tungsten disulfide nanoparticles.'
Inventor(s) include Sunita Rattan; and Jyoti Gupta.
The application for the patent was published on May 30, under issue no. 22/2025.
According to the abstract released by the Intellectual Property India: "The present invention discloses a N-P Junction-Based Chemiresistive Sensor for Vapor Detection Using Functionalized Nano Graphite Platelets and Tungsten Disulfide Nanoparticles. In the present invention, the development of a sensitive and selective p-NP detector by the creation of an n-p junction at the interface of porphyrin-functionalized NGPs and WS2 NPs. In all cited documents, Neither NGPs nor WS2 NPs have been used, mainly cobalt-based nanoparticles, porphyrin-based rGO, graphene quantum dots, and functionalized graphene have been used for completely different applications. But in this invention, octa ethyl cobalt porphyrin functionalized NGPs/WS2 Nanocomposite has been synthesized, creating n-p junction at the interface that has improved the charge transfer phenomenon, sensing response, selectivity, rate of absorption, and desorption of p-NP molecules onto the sensing surface."
