Bode Phase Angle Signaling of a TB Disease Biomarker.

Tuberculosis (TB) is a worldwide burden whose total control and eradication remains a challenge due to factors including false positive/negative diagnoses associated with the poor sensitivity of the current diagnostics in immune-compromised and post-vaccinated individuals. As these factors complicate both diagnosis and treatment, the early diagnosis of TB is of pivotal importance towards reaching the universal vision of a TB-free world. Here, an aptasensor for signaling an interferon gamma (IFN-γ) TB biomarker at low levels is reported.

Bioanalytical methods encompassing label-free and labeled tuberculosis aptasensors: A review.

The high incidence of tuberculosis (TB) infection is of great concern world-wide. The traditional TB diagnostic techniques are not ideal for TB diagnosis in resource-poor countries. This is due to their high complexity, expensive nature, long time duration, poor sensitivity and specificity, as well as their requirement for sophisticated laboratories with special biosafety conditions.

Recent advances in the detection of interferon-gamma as a TB biomarker.

Tuberculosis (TB) is one of the main infectious diseases worldwide and accounts for many deaths. It is caused by Mycobacterium tuberculosis usually affecting the lungs of patients. Early diagnosis and treatment are essential to control the TB epidemic.
