Abstract
The present invention is directed to a nucleic acid detection device and method that incorporates bio-nanosensor technology to detect duplex DNA. The device is particularly applicable in detecting the presence or absence of duplex DNA and its correlation to the diagnosis of infectious diseases. In one embodiment, the infectious disease is Lyme disease or a bacterial or viral infection. The device comprises a bio-nanosensor element comprising ssDNA primed nanotubes, either single walled or multi-walled. The method comprises contacting the bio-nanosensor element with a test solution potentially containing DNA of interest. DNA of interest that hybridizes to the ssDNA results in a measurable change in the electrical properties of the bio-nanosensor. Correlations between the results provided by the device and the presence of disease states can result in rapid diagnosis of diseases such as Lyme disease or foodborne infections such as salmonellosis.
