Researchers at the National Institute of Technology Karnataka, Surathkal (NITK), have developed a groundbreaking biosensor that enables rapid detection of dengue fever in its early stages. This innovative tool promises to improve the timely diagnosis of dengue, a viral disease transmitted through mosquito bites, which remains a significant health concern worldwide.
The biosensor, developed by Prof. Badekai Ramachandra Bhat of the Department of Chemistry at NITK and research scholar Shreeganesh Subraya Hegde, is set to revolutionize dengue detection. Unlike the enzyme-based methods currently available, which have a short shelf life, this device utilizes carbon-based materials derived from biomass. These materials give the biosensor an extended shelf life, making it a cost-effective and scalable solution.
Prof. Bhat explained that the biosensor works using an electrochemical approach, which enhances the precision and reliability of detection. It can identify even trace amounts of the dengue virus in the early stages of infection. “By enabling early and accurate dengue detection, this innovative technology has immense potential to improve patient outcomes and strengthen global disease management efforts,” said Bhat.
This breakthrough technology has already been patented in India as of January 2025, and the researchers are optimistic about its potential for large-scale deployment, particularly in areas heavily affected by dengue. The device is also ready for technology transfer, further expanding its reach. With the rising number of dengue cases, this biosensor could significantly advance global health strategies, offering faster diagnoses and timely medical intervention.
