Photonics.

Our innovative photonics technology measures multiplexed assays from the surface of the microfluidic chips. Our system for illuminating and detecting fluorescence assays is simultaneously simple, affordable, highly reproducible and scalable to large volume manufacturing. 1Drop portable medical diagnostics is robust, multiplexing, easy to use, and affordable. We strongly confine electromagnetic fields to the surface by coupling to propagating or localized surface plasmons. This interaction largely enhances the field intensity and local optical density of states, increasing the excitation rate, raising the quantum yield, and controlling far field angular distribution of fluorescence light emitted by fluorescent labels. This amplifies fluorescence signal accompanying molecular binding events by several orders of magnitude. We shorten detection times and increase sensitivity of fluorescence assays.
