  • System and method for heating, cooling and heat cycling on microfluidic device
    Patent number: 7544506
    Abstract: An integrated heat exchange system on a microfluidic card. According to one aspect of the invention, the portable microfluidic card has a heating, cooling and heat cycling system on-board such that the card can be used portably. The microfluidic card includes one or more reservoirs containing exothermic or endothermic material. Once the chemical process of the reservoir material is activated, the reservoir provides heat or cooling to specific locations of the microfluidic card. Multiple reservoirs may be included on a single card to provide varying temperatures. The assay chemicals can be moved to the various reservoirs to create a thermal cycle useful in many biological reactions, for example, Polymerase Chain Reaction (PCR) or rtPCR.
