MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202511114986 A) filed by Chandigarh University, Mohali, Punjab, on Nov. 21, 2025, for 'multi-stage drug authentication system using quantum dots, edible dna, and ai-based verification.'
Inventor(s) include Mamta.
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 discloses a multi-stage drug authentication system designed to prevent pharmaceutical counterfeiting through integrated pre-use, chemical, and post-consumption verification mechanisms. The system employs a quantum-dot coating on each pharmaceutical unit that generates a unique fluorescent signature under ultraviolet light and undergoes self-destruction upon air exposure. An edible DNA barcode printed on the pill surface provides a secondary chemical verification layer, readable through a low-cost CRISPR-Cas12a portable sequencer. A biological post-consumption authentication stage incorporates engineered probiotics that, upon interaction with the gut microbiome, release a chromogenic marker detectable in urine using a lateral-flow test strip. All authentication data are processed via a smartphone application supported by artificial intelligence and blockchain, enabling secure, adaptive, and tamper-proof verification. The system offers an accessible, cost-effective, and highly reliable solution for detecting counterfeit pharmaceuticals throughout the supply chain."
