NCSR Overview | |
| Optical Probe for Luminescence Detection | ||
|---|---|---|
| Researchers at the National Centre for Sensor Research (NCSR) at Dublin City University have developed a handheld optical probe for chemical sensing applications based on the detection of luminescence from a surface or a thin film. The highly efficient design of the probe results in performance improvements from one to two orders of magnitude compared with conventional (e.g. optical fibre-based) sensor probes. This is a generic platform with exchangeable sensor caps and has been successfully applied to the detection of dissolved oxygen, dissolved carbon dioxide and in-breath oxygen. |  |

| Single Element Multi-analyte Sensor | ||
|---|---|---|
| Researchers at the National Centre for Sensor Research (NCSR) at Dublin City University have developed a novel method of producing a single luminescencebased sensor capable of detecting multiple target species by exploiting the inherent cross-sensitivity of the sensor. The technique can be applied to a broad range of existing optical sensors (e.g., phase fluorometric oxygen sensors) without modification to the sensor chemistry or to the optical configuration and has the potential to markedly improve the sensitivity, reliability and functionality of such sensors. | |

| Ammonia Sensing Technology | ||
|---|---|---|
| Researchers in the National Centre for Sensor Research have developed a novel method of detecting ammonia in the gaseous and liquid environments. The invention combines nanoparticulate polyaniline with an ink-jet printing technique to produce a modified electrode sensor system which has improved fabrication, structural and performance characteristics over other gas sensor systems. The electrodes are a low-cost, flexible platform with a high selectivity for ammonia. | |
