Cambridge, MA – DMI announced today that its spiral vortexer micromixer is now patented. It formally issued as a patent titled, “Microfluidic Passive Mixing Chip” as US Patent No. 9,194,780. The patent protects a novel means of mixing large blood cells in a microfluidic environment. Traditional microfluidic mixers have a difficult time with blood since blood is a lot larger and less diffusion than conventional reagents. Multiple mixing forces are imparted onto blood samples using the spiral vortexer micromixer. This technology was developed with support from NASA and has been tested in zero gravity onboard parabolic flights.
