NanoLyse (2010 – 2013)
NANOPARTICLES IN FOOD: Analytical methods for detection and characterisation
The NanoLyse project is a European collaborative research project which is partly funded by the European Commission under the 7th Framework Programme. It is dedicated to the development of analytical methods for detection and characterisation of engineered nanoparticles in food. Z_GIS has been sub-contracted by the Food and Environment Research Agency (Fera, UK) to tackle one major bottleneck in the analysis of nanomaterials in complex matrices by electron microscopy (EM): The time and effort which is required to assess each of the images manually. This issue is being addressed through the development of an object-based image analysis system to streamline the processing of EM images in a (semi)automated way. The development of the image analysis system, based on the eCognition Architect platform (Trimble Geospatial, Germany), involved a large number of EM images in different nanoparticle-matrix scenarios. A crucial aspect was to understand and ‘teach’ the programme those basic criteria that an expert would use in manual processing of the image to distinguish a nanoparticle from background or from other matrix-related objects.
