About us

Oxford HighQ is a spinout from the University of Oxford’s Departments of Materials and Chemistry that will produce next generation chemical and nanoparticle sensors that offer a step change in fluid-based sensing across a wide range of applications and markets. The company has been awarded £900k of InnovateUK funding* and incorporated in October 2017.

The full Oxford HighQ website is currently under construction. For more information, or to register your interest, please contact us using the address below:

Our technology

Oxford HighQ sensors will offer:

  • Simultaneous measurement of nanoparticle volume, aspect ratio and refractive index – useful for particle analysis and identification and not available with existing fluid-based characterisation techniques.
  • Detection of chemicals in much smaller quantities than existing techniques, increasing the speed and sensitivity of assays.
  • Measurement using only minute liquid sample volumes, making precious samples last longer and simplifying sample collection processes.
  • Sensor elements that are micrometres in size and highly parallelisable, compatible with microfluidic systems and mobile point of care or consumer devices.

Our patent protected sensor technology provides the advantages listed above by utilising optical micro-resonators (“microcavities”) to enhance and control the interaction between light and matter. Sensing is achieved by flowing fluid through a resonator and observing changes to a transmitted laser light signal as chemicals and nanoparticles pass through. An individual nanoparticle can be trapped in the resonator using the optical tweezers effect and studied to measure its hydrodynamic radius, aspect ratio, and refractive index.

Once the required information on the nanoparticle has been obtained, the particle is released and another particle is trapped and measured. In this way a detailed picture can be built of the nanoparticle populations in a fluid sample. Chemicals entering the resonators can be detected in quantities of a few hundred molecules or less, and identified by a range of spectroscopic methods.
