Protea Biosciences Group Inc. recently created a new silicon chip technology that allows researchers to rapidly identify and quantify the number of small molecules that are located within biofluids.

The new technology is called Resonance-Enhanced Desorption Ionization chip, or REDIchip. It uses patented, nanopost array (NAPA) nanotechnology created by Akos Vertes of the George Washington University (GWU) chemistry department. Protea has exclusive licensing to the product.

Protea partnered with General Electric Global Research to use a $14 million DARPA cooperative research agreement under GWU's leadership to create REDIchip’s technology.

“REDIchip technology will greatly improve a researcher’s ability to rapidly detect and quantify small molecules in biofluids in a contaminant-free environment," Protea CEO Steve Turner said. "This breakthrough is made possible by a highly organized, high density nanopost array design that provides 27 million nanoposts for each 2-millimeter spot. The chip provides exceptional sensitivity and reproducibility of results. We are presenting applications data at this week’s ASMS Conference, and plan to commence shipments in Q3 2015.”

The announcement was made at the 63rd American Society of Mass Spectrometry Conference on Mass Spectrometry and Allied Topics, which was hosted in St. Louis.
