MUMBAI, India, Jan. 2 -- Intellectual Property India has published a patent application (202541122271 A) filed by Krupanidhi College Of Pharmacy; and Khalid Imran, Bengaluru, Karnataka, on Dec. 5, 2025, for 'a system and method for colorimetric detection of microplastics in food products.'
Inventor(s) include Khalid Imran; Kirk Lenka Fernandes; and Kavitha Kumari.
The application for the patent was published on Jan. 2, under issue no. 01/2026.
According to the abstract released by the Intellectual Property India: "A portable diagnostic patch is provided for the colorimetric detection of microplastics in food products, comprising a microplastic affinity layer formed from a composite matrix of chitosan, tannic acid, nanoclay, and glycerol, which selectively captures microplastic particles via electrostatic and hydrophobic interactions. An adjacent enzyme-indicator reaction layer, containing a lipase enzyme and a hybrid pH-sensitive dye mixture including curcumin and bromothymol blue in a biopolymer matrix, produces a visible color change upon interaction with the captured particles. A protective micro-mesh layer with microporous dimensions of 10-40 microns filters larger debris, while an activation pad maintains layer separation until manual compression initiates the reaction. This invention provides a rapid, selective, and effective method for detecting microplastic contaminants in food products."
