  • PORTABLE BUOYANCY DRIVEN PCR THERMOCYCLER
    Publication number: 20080176292
    Abstract: A closed loop convective flow thermocycler for amplifying DNA sequences via polymerase chain reaction establishes buoyancy driven flow in response to an applied temperature gradient, so that PCR reagents are continuously cycled among temperature zones corresponding to denaturing, annealing and extension temperatures.

  • Method for mixing fluids in microfluidic channels
    Publication number: 20070263477
    Abstract: Methods and apparatus are provided for mixing fluids. In one embodiment of the invention, a fluid mixer is provided including one or more fluid inlet ports, a curved channel connected to the one or more fluid inlet ports including a first curved channel section and a second curved channel section disposed adjacent the first curved channel section, and an outlet port disposed adjacent the second curved channel section. In another embodiment of the invention, a method is provided for mixing fluids in a channel, including providing a channel having a first curved channel section, and a second curved channel section, providing the two or more parallel fluid streams into the second curved channel section of the channel, mixing the two or more parallel fluid streams in the first curved channel section of the channel, and mixing the two or more parallel fluid streams in the second curved channel section of the channel.

  • Electrophoresis in microfabricated devices using photopolymerized polyacrylamide gels and electrode-defined sample injection
    Patent number: 7005050
    Abstract: The present invention relates to a novel, small-scale, electrophoretic separation system based on photodefined polymers and electrode-defined sample injection. Diffusion and displacement coefficients may be modified by varying the gel concentration, the intensity of the incident UV radiation and the temperature at which the gel is run. The device is an major advance over current technology since it provides for a significant reduction in size of the micro-electrophoresis apparatus and a significant cost savings.
