A multidisciplinary group that includes the University of Illinois at Urbana-Champaign and the University of Washington at Tacoma has developed a novel platform to diagnose infectious disease at the point-of-care, using a smartphone as the detection instrument in conjunction with a test kit in the format of a credit card. The group is led by Illinois Electrical and Computer Engineering Professor Brian T. Cunningham; Illinois Bioengineering Professor Rashid Bashir; and, University of Washington at Tacoma Professor David L. Hirschberg, who is affiliated with Sciences and Mathematics, division of the School of Interdisciplinary Arts and Sciences.
