Wasatch Microfluidics, Inc. develops label-free biomolecular interaction analysis solutions. Wasatch’s Continuous Flow Microspotter (CFM) technology uses flow to print microarray spots. The CFM uses microchannels the size of a human hair to flow protein solutions over a surface. This allows more proteins to attach to the surface, thereby leveraging precious samples and allowing researchers to achieve dramatically enhanced sensitivity. As of 2017, the company changed its name to Carterra, Inc.
