Abstract
The invention relates to a method for verification of particles, in particular of nanoparticles (16), in which a sensor area (15) is made available for this purpose, on which the particles can accumulate. The invention also relates to a sensor arrangement having a sensor area (15) which is suitable for carrying out the method mentioned. The invention provides for a plurality of sensor areas (15) to be arranged, on which particles which each have different characteristics can accumulate. For example, this makes it possible to classify nanoparticles (16) of different size, thus advantageously allowing a statement to be made on the size distribution of the nanoparticles (16) in a nanopowder.
