Scientists Created a Paper-based Tuberculosis (TB) Test

Based on a report in The Economic Times, Healthworld, detecting Tuberculosis (TB) early can allow patients to get medicines they require and help prevent the disease from spreading.

Researchers have created a fast, paper-based test to identify TB that can be read with a smartphone, a technology that is increasingly available in developing economies.

The scientist’s joint gold nanoparticles with fluorescent single-stranded DNA sequences that bind to the genetic material of Mycobacterium tuberculosis, the microorganisms that cause TB.  A smartphone camera was used to examine the color change to determine the bacterial concentration.

Furthermore, researchers also tested a tissue sample from a diseased patient to validate further that the device can be used in the field.
