Water quality

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 real-time control strategies in both catchment management and downstream control of purification. Please visit our Water Pollution Monitoring page for further information.


Measuring drug loading of nanoparticles used for viral loading in vaccines or for targeted drug delivery presents significant challenges. At the moment accurate measurement of drug loading can only be carried out in a laboratory using Transmission Electron Microscopy (TEM) or High Performance Liquid Chromatography (HPLC), which are both expensive and difficult to use, limiting the characterisation of new drugs and vaccines and unsuitable for
in-line quality control..

Optical Microcavity analysis is a cost effective and easy to use characterisation technique, allowing fast and accurate measurement of of particle size and drug loading. For more information, please visit our Nanomedicine page. 


Microcavity technology can be used to amplify the signal provided by a wide range of biomarker sensing methods. The miniscule sample quantities required provide new opportunities for biodiagnostics where samples are often scarce and difficult to obtain. We seek partners in this field to discuss potential applications.

Defence & Security

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.

We are currently investigating the feasibility of combining immunoassays with optical microcavity technology to detect trace amounts of suspect material in solution. Ideally this methodology will be quantitative, and our microcavity enhancement will result in significantly reduced detection limits compared to existing immunoassaybased detection.
