Micronics, Inc. today
announced that it has been issued a second letters patent from the United States
Patent and Trademark Office (USPTO) for an integrated heat exchange system on
a disposable, plastic cartridge. The new patent has broad utility across the
life sciences sector with particular application in point of care molecular
The patent, entitled "System and method for heating, cooling and heat
cycling on a microfluidic device," is U.S. Patent No. 7,648,835 (the '835
case). The newly issued patent identifies the use of exothermic or endothermic
material in reservoirs that are contained within an integrated disposable plastic
cartridge. Once the chemical process of the reservoir material is activated,
the reservoir provides heating or cooling to specific locations on the cartridge.
Multiple reservoirs may be included in a cartridge to provide varying temperatures.
Micronics is employing this technology in the development of disposable cartridges
for performance of a complete polymerase chain reaction (PCR) temperature cycle
in less than 15 seconds.
The '835 case is related to an earlier patent, U.S. Patent No. 7,544,506,
also issued to Micronics. The devices of these patents make it possible to perform
PCR or rtPCR in a fraction of the time of commercial systems in use today. In
Micronics' molecular diagnostic devices, all reagents required for a diagnostic
test are incorporated into the disposable cartridge.
Micronics is advancing a point of care molecular diagnostic platform, called
the PanNAT system, that employs disposable cartridges and a small, lightweight,
easy to operate instrument. Using microfluidics, the Company is able to substantially
reduce the volumes of sample and reagents required to produce a test result,
generally within a fraction of the time and cost that traditional reference
lab and bench top methods require.
Micronics is advancing a unique portfolio of point of care molecular diagnostic
tests for infectious disease detection, diagnosis and treatment monitoring.
The Company has developed a significant patent estate in microfluidics and related
technologies that enable the direct processing of biological and environmental
samples, and the performance of highly accurate tests in a fraction of the time
required by most molecular diagnostic tests in use today. The Company also provides
custom product development on behalf of clients worldwide.
