Cluster: Sensor Technology 1

Accurate and rapid detection of contaminants in food products is necessary, but often cumbersome and a technically complex process. Current gold standard methods are typically based on highly specific, but expensive lab techniques, which are able to detect contaminants in different complex samples. Rapid and affordable alternative methods, mostly based on dipstick tests, are not accurate enough and can detect only one parameter/analyte. The recent fibronil affair illustrates that, despite the technological advances in detection technology, there is still a need for low-cost, fast and reliable tests for routine screening of food products.

During this project, you will be contributing to the development of a portable demonstrator based on existing photonic biosensor prototypes. The developed demonstrator, consisting of a Lab-on-a-Chip system and a read-out detector, will first be tested with standard/spiked samples. Next, it will be calibrated and validated with complex samples, e.g. whey/milk, and finally benchmarked with gold standard methods. Furthermore, it will be investigated how this portable demonstrator can be applied for rapid antibiotics detection at point-of-need settings such as dairy farms.
