Device for Smartphone Identifies Cancer with 99 Percent Accuracy

5 nov 2016 – Researchers have developed a smartphone add-on that allows doctors to detect interleukin 6 with 99 percent accuracy.  Interleukin 6 (IL-6) has been linked to prostate, liver, carcinoma, and lung cancers.

The rig uses a smartphone, prism, and an enzyme-linked immunosorbent assay (ELISA) plate. The backlit ELISA plate has 96 wells and can process up to eight samples at any given time. The technicians use a spectrometer app on the smartphone to analyze each well for color change.

Lei Li, assistant professor in the School of Mechanical and Materials Engineering at Washington State University, said the device is more efficient than other spectrometer counterparts.

“With our eight channel spectrometer, we can put eight different samples to do the same test, or one sample in eight different wells to do eight different tests. This increases our device’s efficiency,” said Li.

Li said he filed a provisional patent for the team’s design. The initial design used an iPhone 5, but Li hopes he and his team can create a universal design usable with any smart device. Li said the device could be crucial in detecting IL-6 in remote areas or for mobile clinics.
