Chemical Sensing

Our sensors are based on optical microresonators, which can amplify signals in any of the wide variety of optical methods commonly used in chemical sensing. While the use of optical microresonators in sensing is not a new idea, the Oxford HighQ team has pioneered methods for resonator fabrication and use that will make microresonator-enhanced sensors a commercial reality for the first time.

Optical Microcavity Analysis (OMCA) promises:

  • Orders of magnitude increase in the sensitivity of optical sensing methods

    such as colorimetric absorption assays.

  • Measurement using only minute liquid sample volumes, making precious

    samples last longer and simplifying sample collection processes.

  • Sensor elements that are microns in size and highly parallelizable,

    compatible with microfluidic systems and chip-scale devices.

    The technology represents a universal platform for chip-scale chemical and nanoparticle sensing. Sensors can be configured to detect a wide range of chemical and particle species of interest, from heavy metal pollutants to micron sized particles such as bacteria.
