As the result of the work of ASU researchers over the past two years, three companies are moving toward commercialization of new testing tools methods to more effectively and quickly reveal if people have contracted COVID-19. One of the companies, Flex Bio Systems and Tech was co-founded by Jennifer Blain Christen, a Fulton Schools associate professor of electrical and computer engineering and director of ASU’s BioElectrical Systems and Technology group. She and her team now have working prototypes of small, portable test machines for saliva samples that can be read by scanners to reveal if results are positive, negative or in error for early indicators of COVID-19 infection.
