Signal amplification provided by OMCA allows existing colorimetric tests to be performed with miniscule quantities of reagent. We are developing nitrate and phosphate sensors with very long autonomous operation cycles, promising lower operating costs and simpler instrumentation. As a consequence, we envisage users will be able to get closer to the real-time control strategies in both catchment management and downstream control of purification.
SECURITY & DEFENCE
From capability in ordnance or pathogen detection to illegal drug identification, the potential of optical microcavity analysis in providing small, portable and low cost sensing is clear.
