Revolutionary TB Detection Device
A team of researchers at Tezpur University in Assam has developed a groundbreaking portable device to detect tuberculosis using a smartphone. This innovative solution is cost-effective, priced under Rs 25,000, and weighs less than 300 grams.
How It Works
Unlike traditional methods, this new device does not require any chemicals or dyes for detection. It utilizes the natural glow (autofluorescence) of TB bacteria, making it highly efficient. Professor Pabitra Nath, leading the team, highlighted the device’s built-in heating system, enhancing the detection process.
The compact and lightweight design of this device makes it ideal for areas with limited healthcare infrastructure, providing early and accurate diagnosis of TB—a significant public health concern in India.
Advantages Over Traditional Methods
While LED fluorescence microscopy is currently the gold standard for TB screening, it has limitations such as costly equipment and the need for trained personnel. The device developed at Tezpur University leverages autofluorescence principles, eliminating the use of stains or dyes for detection.
The integration of a heating element within the sensor further enhances the natural fluorescence signal from TB cells, enabling trace-level detection with high accuracy. The research team has already filed a patent for this innovative device, showcasing its potential impact in the fight against TB.
Published in an international journal, Biosensors and Bioelectronics, this research represents a significant step forward in combating TB, particularly in rural areas where access to healthcare facilities is limited.
