Towards portable rapid TB biosensor: Detecting Mycobacterium tuberculosis in raw sputum samples using functionalized screen printed electrodes
Due to lack of robust, sensitive and low cost detection strategies, Tuberculosis (TB) remains
a significant global health issue. WHO reports 1.5 million deaths per year,∼ 80% cases
occur in low-to middle-income countries, where resource limitations complicate the
diagnosis. Robust detection of TB infection is important to contain the spread and treat
disease. We developed a label-free DNA biosensor based on commercially available
screen printed electrodes (SPEs)(DropSens and Zensors) that can detect TB robustly …
