A testing device that integrates nucleic acid isolation, isothermal amplification and detection wherein a sample and reagents are transported through a capture/binding membrane by capillary forces and the positioning of a slidebar that supports said binding membrane. Flow control and fluid actuation are effected by the position of said slidebar which makes a fluidic connection through the capture membrane situated between a reservoir of liquid on the device and an absorbing pad, and where a sequence of operations for sample loading, washing, optionally amplification, and optical detection of analytes can be done conveniently and rapidly at the point of care. With minimal operator interaction, this device can lyse, isolate, amplify, and detect nucleic acids from clinical specimens and environmental samples. |
