McCain and Obama on Bio-threat Detection and Pandemic Response: QualSec Weighs In

CHAPEL HILL, N.C. -- September 23, 2008 -- Electronic nose innovator QualSec (OTC: QLSC.OB) has noted the recent responses from presidential candidates Barack Obama and John McCain at Science Debate 2008 and weighs in on their reactions to questions about bio-security and pandemic prevention, and the crucial role of technology in fighting these threats.

"Samples from currently-deployed detectors must be collected by hand and analyzed in laboratories. This can mean that up to 30 hours elapses between when a biological agent is released and when it is analyzed and identified in a lab," said McCain.

He continued: "We need to continue to develop and facilitate the development of next generation automated detectors that can analyze as well as sample biological agents and feed information real-time to public heath and emergency management officials."

On the crucial importance of time in bio-threat detection, QualSec believes that McCain is right.  The company's handheld, easy-to-use NanoNose utilizes breakthroughs in nanotechnology to analyze and quantify airborne particles in seconds instead of hours, giving homeland security or public health agencies the edge they need.

As noted in Homeland Security Today, QualSec's patented NanoNose is unique in its ability to provide real-time on-site analyses never previously offered by electronic nose manufacturers. The NanoNose also requires no extensive training for accurate usage.

Obama also reflected upon the importance of technology in bio-terror and pandemic response, saying he "will invest in new vaccines and technology to detect attacks and to trace them to their origin, so that we can react in a timely fashion."

Both candidates cite the need for the technology. What if they knew that it is already out there?
