MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202511114408 A) filed by Graphic Era, Dehradun, Uttarakhand, on Nov. 20, 2025, for 'a portable system and method for on-site detection of salmonella in food using microfluidic sample processing, biosensors, ai data processing, and wireless connectivity.'
Inventor(s) include Rahul Kumar; Pankaj Gautam; Debasis Mitra; and Sourav Chattaraj.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "The invention relates to a portable system for detecting Salmonella in food, integrating a sample input and microfluidic processing unit with a sample input port and a microfluidic cartridge containing microchannels for mixing food samples with preloaded reagents, and a biosensor array with immobilized capture elements to transduce binding events into electrical or optical signals. A signal processing and data acquisition module with amplifiers and analog-to-digital converters digitizes the sensor outputs, which are then analyzed by an AI-driven analytics module executing machine learning algorithms for pattern recognition and quantification. A user interface displays the results while a wireless connectivity module (Wi-Fi/Bluetooth) transmits the data, and a battery-powered supply module ensures portable operation for effective on-site food safety testing."
