MUMBAI, India, June 30 -- Intellectual Property India has published a patent application (202621054077 A) filed by Sage University on April 28, 2026, for Apparatus And Method For Detection Of Pathogenic Microorganisms In Food Samples.
Inventors include Dr. Prashant Jain; Ms. Sakshi Agrawal; Payal Jaishwal; Aisha; and Divyanshu Kumar.
The application for the patent was published on June 26, 2026, under issue no. 26/2026.
Abstract: ABSTRACT The present disclosure relates to detection of pathogenic microorganisms in food samples. The apparatus (102) includes a dual-sensor cartridge (104) that directs a food sample concurrently to a screen-printed electrode array (106) generating amperometric current signals and a chromogenic detection membrane (108) producing a colorimetric response, operating as independent detection modalities. A potentiostat circuit (110) measures the amperometric current signals, while an ambient light sensor (112) generates an illumination signal corresponding to ambient illumination. A reader instrument (114) with a hardware processor (116) receives the amperometric current signals and illumination signal, compares the signals to threshold criteria to generate a pathogen detection result, and determines which detection modality serves as the primary verifiable modality based on ambient illumination. The apparatus operates under variable illumination, self-contained electrical power, and vernacular operator interaction, enabling pathogen detection across locations with variable infrastructure availability.
