See What Makes Plasmonic Diagnostics Different

Faster Detection

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


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.
