MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202611048786 A) filed by Dr. Shipra Rohatgi, Noida, Uttar Pradesh, on April 16, for 'nanoparticle-based composition and method for multi-surface latent fingerprint detection and visualization.'
Inventor(s) include Dr. Shipra Rohatgi; Nivedhetha Rajendran; Dr. Baljeet Yadav; Sadaf Vakil; Anurag Gupta; Neha Gupta; Dr. Sameer Saharan; and Dr. Poonam Yadav.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The present disclosure relates to a method (100) and a fingerprint detection powder composition for developing and visualising latent fingerprints on a surface. The method includes applying a fingerprint detection powder onto a surface suspected of containing latent fingerprints, allowing nanoparticles present within the powder to selectively bind with chemical constituents of fingerprint residues, removing excess powder using brushing or air-assisted removal, and visualising developed fingerprint ridge patterns under visible light or ultraviolet illumination. The fingerprint detection powder includes metal oxide nanoparticles selected from zinc oxide, titanium dioxide, iron oxide, or combinations thereof, fluorescent nanoparticles comprising quantum dots, silica nanoparticles for improving dispersion and adhesion characteristics, carrier materials, and a polymer stabilizer. The nanoparticles selectively adhere to residues including sweat, lipids, amino acids, and proteinaceous materials to generate visible ridge patterns. The composition supports effective fingerprint development across multiple surface types including glass, plastic, metal, paper, fabric, and polymer materials."
