Cancer Center at Illinois and Mount Sinai researchers have developed a low-cost, portable, point-of-care technology capable of diagnosing early-stage liver cancer within 30 minutes. The study, led by Brian Cunningham, Cancer Center at Illinois program leader and professor of electrical and computer engineering, and Carl R. Woese Institute for Genomic Biology (IGB) postdoctoral fellow Bin Zhao, uses a toaster-sized device comprised of a red LED light, microscope objective, and webcam to detect gold nanoparticles (AuNPs) that attach to target RNA.
