MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202621060816 A) filed by Sage University on May 13, 2026, for Apparatus And Method For Electrochemical Detection Of Multiple Pathogenic Microorganisms In Food Sample.
Inventors include Dr. Prashant Jain; Ms. Sakshi Agrawal; Dr. Nirmal Dongre; and Dr. Nidhi Bais.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: ABSTRACT The present disclosure relates to electrochemical detection of multiple foodborne pathogens. The apparatus (100) includes a disposable sensor cartridge (102) having an immunomagnetic separation chamber (104) in direct fluidic communication with a detection chamber (106). The detection chamber (106) houses a screen-printed electrode array (108) with at least four working electrodes (110), each functionalized with capture antibodies targeting a distinct pathogenic species. An electromagnet array (112) aligns with the separation chamber (104), while a pump (116) and potentiostat (118) manage fluid delivery and electrochemical measurement, respectively. A microprocessor (120) coordinates pulsed flow actuation to capture pathogen-bound immunomagnetic beads, then transfers a concentrated pathogen suspension to the detection chamber (106). Enzyme-conjugated detection antibodies form sandwich immunocomplexes on the working electrodes (110), and the potentiostat (118) measures amperometric current responses to simultaneously determine presence or absence of multiple target pathogens in a single food sample analysis.
