Integrated Nano-Technologies announces acquisition of patents and completion of prototype

Keywords: Biosensors, DNA

Integrated Nano-Technologies has announced that it has acquired a suite of patents that will establish it as the leader in electronic DNA detection. At the same time, INT is completing its development of BioDetect™, a new DNA-based testing system that will rapidly and accurately test for the presence of biological pathogens, such as the virus that causes severe acute respiratory syndrome (SARS) as well as anthrax and smallpox. This system will fill a substantial void in current methods of detection, which are slow, lab-based, and expensive. The BioDetect™ system will return results in less than 30 min, and is small enough to be carried for outdoor use or installed in air circulation systems. INT has been developing BioDetect™ for the past 2 years, during which time world events have further underscored the need for such a system.

Recently, INT acquired a collection of patents from Technion (Israel Institute of Technology), which covers the metallization of DNA. Technion's ground breaking work in this field has been recognized through publications in the journals "Science" and "Nature". These technologies, when combined with INT's expertise in chip fabrication and molecular biology will produce an entirely new sensor that lies at the heart of BioDetect™.

"Traditional biological agent detection systems involve sending samples to laboratories, where they undergo a complex testing process that can take up to 24 h to complete," said Michael Connolly, CEO of Integrated Nano-Technologies. "The BioDetect™ system will generate results in the field substantially faster and with greater accuracy than any existing system or test."

The BioDetect™ system will be a field-portable, electronic-based DNA detection system that can test air, liquid or solid samples. The system uses disposable test processing cards and weighs approximately 20 pounds. The system will be able to test for the presence of biological agents, including the SARS virus, anthrax, and smallpox in as little as 30 min. Commercial availability is expected by the end of 2003. Future versions of the system will enable the medical community to identify additional illness- causing pathogens in patients without sending samples to laboratories.
