Development and evaluation of a loop-mediated isothermal amplification combined with au-nanoprobe assay for rapid detection of .

Loop-mediated isothermal amplification (LAMP) has been proposed as an inexpensive and easy to perform assay for molecular diagnostics. We present a novel strategy for the detection of LAMP amplicons derived from Mycobacterium tuberculosis by the use of Au-nanoprobes. When applied to a total of 93 clinical specimens, the LAMP assay demonstrated sensitivity and specificity higher than that of polymerase chain reaction and culture.

Detection of Mycobacterium tuberculosis by using loop-mediated isothermal amplification combined with a lateral flow dipstick in clinical samples.

Tuberculosis (TB) is a communicable disease caused by the bacterium Mycobacterium tuberculosis (MTB) and is a persistent problem in the developing countries. Loop-mediated isothermal amplification (LAMP) allows DNA to be amplified rapidly at a constant temperature. Here, a LAMP method was combined with a chromatographic lateral-flow dipstick (LFD) to detect IS6110 gene of M.

Detection of non-amplified Mycobacterium tuberculosis genomic DNA using piezoelectric DNA-based biosensors.

Piezoelectric DNA-based biosensor technology was developed as a new method for detection of M. tuberculosis. This method consists of immobilizing a thiol-modified oligonucleotide probe on the gold electrode surface of a quartz crystal, using a self-assembled monolayer method.
