Nano Method Decision Tool


ACEnano will introduce confidence, adaptability and clarity into nanomaterial risk assessment by the creation of a “conceptual toolbox” including a tiered approach to cost efficient nanomaterial analysis that will, among others, facilitate decision-making in choice of the measurement techniques. This includes this decision tool that will guide users through the selection of the most appropriate methods to address their needs in material registration, risk assessment or product labelling. The focus of the Nano Method Decision Tool, which is based on the NanoDefiner e-tool, is the recommendation of a suitable measurement techniques based on a material description by the user. Based on the interest of the user three categories are available, “Regulation”, “Risk Assessment” and “Labelling”. For each of these a set of parameters needs to be determined and is shown in a second window. For instance, for regulation these are: size and size distribution, shape and aspect ratio, surface functionalisation and surface area. By selecting a parameter, a third window is opened containing a series of questions that essentially form a description of the material properties, and a list of measurement techniques that are able to determine the parameter. Based on the answers to the questions one or more of these techniques will be suggested as a suitable measurement technique for the parameter with the described type of nanomaterial.
