Changing the way biomarkers are detected

Our noninvasive, ultra-sensitive, and low-cost molecular detection system can detect LAM in urine.  This innovative diagnostic system is based on a fluorescent sandwich ELISA assay which is simple and easy to use.

Faster Detection

Our technology speeds up the time-to-detection through intrinsic signal amplification, reduced scattering, high signal-to-noise ratio, and directional emission.

Ultra-Sensitive

The sensitivity of P-GRAT is three orders of magnitude lower than commercially available ELISA kits.

Low Cost

Our simplified design excludes expensive optics, lasers, and lenses by using 3D-printed parts and a smartphone camera as the detector.

Making an Impact Across the Globe

The World Health Organization (WHO) reported 9.6 million people were taken ill and another 1.3 million died from Tuberculosis in 2016.


Our non-invasive, inexpensive P-GRAT technology offers a leading opportunity in the tuberculosis detection market. P-GRAT can also be manipulated to include specific biomarkers for other infectious diseases.

By the Numbers

Standard TB culture tests typically require days to yield results while the more sophisticated molecular diagnostic tests are fast but very expensive.  Our system has high specificity, ultra -sensitive detection and provides results in a few hours, making it a substantive innovation in the current TB molecular diagnostic market.
