MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202641001546 A) filed by Saveetha Institute Of Medical And Technical Sciences, Chennai, Tamil Nadu, on Jan. 7, for 'saliva based non invasive monitoring of type 2 diabetes mellitus and methods thereof.'
Inventor(s) include Dr Jayasri D; Dr Ranjith R; Dr. Nisha B; and Deepak Nallaswamy Veeraiyan.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses a saliva-based, non-invasive glucose monitoring system incorporating a surface-functionalized nanogold biosensor, specifically designed for early detection and large-scale screening of Type 2 Diabetes Mellitus (T2DM). The system employs gold nanoparticles functionalized with glucose-specific recognition elements, including enzymes, aptamers, or boronic acid derivatives, which selectively bind to glucose molecules present in human saliva. Upon binding, measurable optical or electrochemical signals are generated, which are subsequently processed by an integrated signal detection and readout unit within a portable device. The invention eliminates the need for invasive fingerprick sampling, providing a painless, cost-effective, and user-friendly alternative. Additionally, the system includes disposable saliva collection strips, calibration modules, and optional wireless connectivity for real-time data management. This platform offers a scalable diagnostic solution suitable for individual self-monitoring, clinical applications, and population-level diabetes screening, thereby improving accessibility, patient compliance, and preventive healthcare outcomes in both resource-limited and advanced healthcare settings."
