Advanced Chemical Sensor Technology

Advanced nanodroplet based sensing platform

The technology makes it possible to continuously measure chemical and biological molecules with a high level of accuracy, leading to applications including wearable devices that monitor the glucose and drug levels of the body as well as non-medical uses such as remote pollutant sensors for our rivers and oceans.

Wearable technologies are increasingly available in our modern society to record our heart rate and physical activity, but it remains extremely difficult to effectively monitor the continuous chemical changes of the body or the effectiveness of medical drugs.

Dr Xize Niu founded SouthWestSensor (SWS) Limited, an ambitious spinout that has created proprietary and patented technologies for portable and wearable sensors that are able to monitor chemicals in fluids in real-time.

Continuous, real-time measurement of biomolecule levels from blood or tissue fluids would accelerate the understanding of fundamental physiological and pathological processes, empowering healthcare professionals to make faster and potentially life-saving interventions.

Current detection technologies rely on expensive medical equipment and infrequent one-time measurements that may miss out vital information, leading to wrong diagnosis and poor treatment.

SWS Approach

  •  We have developed Nanodroplet based sensor technology. Droplets can be used as discrete bioreactors for high frequency sensing of key chemical & biological markers
  •  Presence of target in the droplets can be quantified via colour change & optical read-out
  •  We have developed controlled pumping & autonomous device architecture which is key for reproducible & robust results

Key attributes:

☑ Platform compatible with most assay formats
☑ Fully quantitative with high sampling frequency
☑ Small (portable/wearable), low power & reagent consumption, low cost
