Abstract Background HIV-associated immune defects inhibit tuberculosis (TB) diagnosis, promote development of extrapulmonary TB and paucibacillary pulmonary TB cases with atypical radiographic features, and increase TB relapse rates. We therefore ass

Conventional friction force microscopes (FFMs), where micro cantilever probes are used, have a disadvantage that the accurate quantification of friction force has not been established yet. This comes from the difficulty of measurement of the probe to
