Portable TB Detection Device Uses Smartphones For Diagnosis
Imagine a tiny, portable tool that can find TB, a disease that can make people sick.
Scientists created a device that works with smartphones to spot TB germs.
It uses a special light to see the germs glow naturally, without needing any messy chemicals.
This new tool is small, easy to carry, and can be used in places that don't have fancy labs.
By heating up the sample, it helps the device find even tiny amounts of TB, making it easier to stop the spread of the disease, especially in areas with limited healthcare.
Researchers at Tezpur University developed a portable TB detection device.
The device utilizes smartphone integration for testing and analysis.
It detects TB using the autofluorescence of TB bacteria, eliminating the need for chemicals.
The device includes a built-in heating system to enhance detection.
The cost is under Rs 25,000 and weighs less than 300g, making it suitable for rural areas.
