MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202611001448 A) filed by Shree Guru Gobind Singh Tricentenary University, Gurugram, Haryana, on Jan. 6, for 'nanohybrid for development of latent fingerprint and method synthesis thereof.'
Inventor(s) include Dr. Neha; Mohd. Jamshaiya Raza; and Dr. Chandra Mouli Pandey.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "A nanohybrid for development of latent fingerprint comprising zinc oxide nanoparticles ZnO NPs and dithizone DTZ in a ratio ranging from a lower limit to an upper limit is disclosed, wherein DTZ molecules are coordinated to ZnO nanoparticle surfaces via nitrogen and or sulfur atoms to form a ZnO-DTZ nanohybrid, ZnO nanoparticles exhibit an average particle size between 20-45 nm and ZnO-DTZ nanohybrid exhibits a hydrodynamic diameter of 43 nm, nanohybrid provides high contrast visualization of latent fingerprints with excellent background suppression and adheres strongly to porous substrates such as paper maintaining fingerprint clarity for at least 24 hours, nanohybrid is suitable for forensic applications on glass PVC wood and metallic surfaces, a green synthesis method is described involving bay leaf extract assisted formation of ZnO nanoparticles DTZ coordination centrifugation optional calcination at 300-500 C and drying at 40-50 C to obtain a fine pink to reddish powder."
