Inventor(s) include Ms. Smitha Shibu; Dr. P. Pavitra; Dr. S. Manimaran; Dr. K. A. Emmanuel; Dr. Nagaroor Vijayalakshmi; Dr. Jaggi Lal; Prof. Dr. Sharad S Sankhe; Dr. G. Sasikumar; and Dr. A. Mushira Banu.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a nanogold colloid for responding to heavy metal ions and a preparation method thereof. The nanogold colloid comprises uniformly dispersed gold nanoparticles with controlled size and high colloidal stability, enabling selective and sensitive interaction with toxic heavy metal ions in aqueous and environmental samples. Upon exposure to heavy metal ions, the nanogold colloid exhibits measurable optical changes, including color variation and plasmonic shift, allowing rapid and simple detection without the need for complex analytical instruments. The preparation method ensures reproducibility, scalability, and long-term stability of the colloidal system, overcoming limitations of conventional heavy metal detection techniques such as high cost, complexity, and lack of portability. The proposed invention is suitable for real-time and on-site monitoring applications and can be integrated into portable sensing platforms. The nanogold colloid provides a cost-effective, user-friendly, and reliable solution for environmental monitoring, industrial effluent analysis, food safety testing, and public health protection."
