After Andraka’s proposal to build and test his idea for a pancreatic cancer detector was rejected from 199 labs, the teen landed at Johns Hopkins. There, he built his device using inexpensive strips of filter paper, carbon nanotubes and antibodies sensitive to mesothelin, a protein found in high levels in people with pancreatic cancer. When dipped in blood or urine, the mesothelin adheres to these antibodies and is detectable by predictable changes in the nanotubes’ electrical conductivity. In preliminary tests, Andraka’s invention has shown 100 percent accuracy. It also finds cancers earlier than current methods, costs a mere 3 cents and earned the high schooler the 2012 Intel Science Fair grand prize. "This kid is the Edison of our times. There are going to be a lot of light bulbs coming from him" Dr. Anirban Maitra, Johns Hopkins University, The Baltimore Sun 5/24/2012
