Analyzer That Plugs Into a Smartphone Takes the Lab to the Field

The spectral Transmission-Reflectance-Intensity (TRI)-Analyzer, developed at the University of Illinois at Urbana-Champaign, attaches to a smartphone and can perform blood, urine, and saliva tests on human beings as reliably as lab instruments.

The system is capable of detecting the results of any test that uses a liquid that changes color or a liquid that generates light, such as the glow from fluorescent dyes. In addition to standard CBCs and UAs, the TRI-Analyzer can perform ELISA assays and can be adapted to perform point-of-use tests for veterinarians, monitor environmental conditions, perform drug tests, and monitor quality control and food safety.

The device works by converting the smartphone camera into a high-performance spectrometer. The analyzer illuminates a sample fluid with the phone’s internal white LED flash or an inexpensive external green laser diode. The light from the sample is collected in an optical fiber and guided through a diffraction grating into the phone’s rear-facing internal camera. All these optical components are arranged within a 3D-printed plastic cradle. The device can simultaneously measure multiple samples by using a microfluidic cartridge that slides through an opening in the back of the cradle and past a readout head, similar to the way magnetic strip credit cards are swiped.

The technology is patented and available for license, and the retail cost for each device is $550.
