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 diagnostics.
“System and method for heating, cooling and heat
cycling on a microfluidic device”
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
