Tezpur University Develops Low-Cost TB Detection Device
Scientists at Tezpur University created a new tool to find TB, a disease that makes people sick.
It works with a smartphone and doesn't need expensive equipment or chemicals.
The device uses the natural light that TB germs give off to find them.
It's small, easy to carry, and costs less than Rs 25,000.
This makes it perfect for villages and places where there aren't many doctors or hospitals.
This new invention could help find and stop TB from spreading, especially in areas that need it most.
Tezpur University researchers developed a low-cost, portable device to detect Tuberculosis (TB) using a smartphone.
The device uses the natural glow (autofluorescence) of TB bacteria for detection, eliminating the need for chemicals or dyes.
It includes a heating system to improve test accuracy and is designed for use in rural and remote areas.
The device is cost-effective, costing under Rs 25,000 and weighing less than 300 grams.
The research team has filed a patent for the device and published their findings in an international journal.
