Portable labs become reality

Portable labs are here.

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 analyses the amount and type of chemicals in a sample by measuring the light spectrum.

Although 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 colour change as disease markers.
