Purdue University researchers have developed a laser-induced breakdown spectroscopy (LIBS) method for characterizing both cytokines, molecules that are released in an immune response, and food contaminants. Food fraud has severe health-related consequences; in 2007-2008, a dairy contaminant added to raise nitrogen content had an estimated 300,000 human victims. Cytokine detection can be used as an indicator for COVID-19 infection. However, cytokine tests for COVID-19 require extensive processing time and are expensive. The Purdue technology showed an acceptable detection limit using a portable unit, and it showed high accuracy in food product fingerprinting. Finally, this technology is portable, avoiding the need for sending the food/biological samples to an established laboratory.

Technology Validation: The technology showed a higher detection limit than conventional cytokine detection tools, and it showed high accuracy in food product fingerprinting.
