Tuberculosis (TB) is an important disease worldwide. Currently, one-third of the world’s population is infected with TB, and it is a leading cause of death among people living with HIV. Immediate but also accurate diagnosis is required for disease control, yet available diagnostics cannot do both simultaneously. Therefore, designing a technique that can diagnose the disease correctly in the shortest possible time is in great demand in order to stop its spread. Diffraction-based sensing is a novel technique for measuring of biomolecular interaction that has potential for disease diagnosis. In this study, diffraction-based sensing successfully demonstrated its usefulness for diagnostics of TB using recombinant TB antigen, or by detection of interferon-γ that is produced from white blood cells when the immune system activates. The feasibility of the technology was also evaluated in terms of providing real time observation, reducing diagnostic duration, and increasing sensitivity of detection.
