Detailed Technology Description

Micropatterning devices are invaluable tools in: DNA applications, Lab on a Chip applications, and protein microarray applications. However, there are improvements that can be made in low throughput patterning and reagent crosstalk and contamination. In addition, currently micropatterning is a time-consuming serial process, with low repeatability and reproducibility. Researchers at University of California, Davis have addressed these limitations, while additionally designing a lower cost device. By using a dot matrix printer head with a microfluidic-ribbon device, we can replace conventional expensive systems (laser, robotic hand, etc.), while producing similar-quality patterning and performance. This new device can be used with a total sample volume in the microliter or sub-microliter scale (compared to a standard cartridge of an ink-jet printer which is in the milliliter scale). Washing of the printing device (which is required in robotic printing) is not required here, thereby dramatically reducing the laborious work of the operator.
