MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641047912 A) filed by NITTE, Mangaluru, Karnataka, on April 15, for 'ai-based smart imaging system for rapid detection of microplastics in water samples.'
Inventor(s) include Dr. Sneha Nayak; Nathan Immanuel D'Souza; Medha C Adiga; Meka Lakshmi Charitha; and Manya Pramod Bharadhwaj.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "Disclosed herein is an AI-based smart imaging system (100) for rapid detection of microplastics in water samples, comprising a sample preparation unit (102) comprising a membrane filter (104) configured to stain a water sample with Nile Red dye and concentrate microplastic particles through vacuum-assisted filtration, a fluorescence imaging unit (106) configured to capture fluorescence microscopy images of the stained membrane filter (104) under UV excitation, and a processing unit (108) comprising an input module (110), a preprocessing module (112) configured to perform contrast enhancement, noise reduction, and image resizing, a detection module (114) configured to execute a trained deep learning object detection model and apply a two-parameter validation comprising a minimum confidence score threshold and a minimum fluorescence intensity threshold to reject false-positive detections, a classification module (116) configured to sub-classify detected particles into fragment, fiber, or film morphological categories, a quantification module (118), and an output module (120)."
