Abstract
The objective of this study was to demonstrate proof of concept for the Integrated Nano-Technologies BioDetect Bacillus anthracis electronic DNA sensor. B. anthracis Ames strain DNA was successfully detected by the formation of DNA bridges on the sensor. The bridges were coated with metal, resulting in a significant drop in electrical resistance. In this small test, at a relatively high DNA concentration, the overall accuracy of the sensor was 90.7%. The technology shows significant promise for future development as a bio-agent detection system.
