Smartphones May Soon Detect Cancer

The capabilities of smartphones are increasing every six months. From GMO detection and viruses, an extension to elaborate laboratories may soon be readily available in the palm of your hands. Washington State University researchers have now developed a low-cost, portable laboratory on a smartphone that can analyze several samples at once to catch a cancer biomarker, producing lab quality results.

“Modern biological research is also allowing an extension of laboratory devices on to small computer chips to detect biological information within DNA sequences,” said biotech specialist Dr. Marek Banaszewski. “Bioinformatic algorithms within programs will aid the identification of transgenes, promoters, and other functional elements of DNA, making detection of genetically modified foods on-the-spot and real-time without transportation to a laboratory.”

Other research, previously published in the American Chemical Society’s journal ACS Nano, includes a cellphone camera enabled sensor for allergens in food products and a smart phone attachment that can conduct common kidney tests.

The research team, led by Lei Li, assistant professor in the School of Mechanical and Materials Engineering, recently published the work in the journal Biosensors and Bioelectronics.

At a time when patients and medical professionals expect always faster results, researchers are trying to translate biodetection technologies used in laboratories to the field and clinic, so patients can get nearly instant diagnoses in a physician’s office, an ambulance or the emergency room.

The WSU research team created an eight channel smartphone spectrometer that can detect human interleukin-6 (IL-6), a known biomarker for lung, prostate, liver, breast and epithelial cancers. A spectrometer analyzes the amount and type of chemicals in a sample by measuring the light spectrum.

lthough smartphone spectrometers exist, they only monitor or measure a single sample at a time, making them inefficient for real world applications. Li’s multichannel spectrometer can measure up to eight different samples at once using a common test called ELISA, or colorimetric test enzyme-linked immunosorbent assay, that identifies antibodies and color change as disease markers.

Although Li’s group has only used the smartphone spectrometer with standard lab-controlled samples, their device has been up to 99 percent accurate. The researchers are now applying their portable spectrometer in real world situations

  1. Since they possibly cause cancer, then I guess it comes in handy….
