Nanoparticle analysis is an important challenge in the present nanoscale metrology. It is shown that the elimination of user influence on the data processing algorithm is a key step for obtaining accurate results while analyzing nanoparticles measured in non-ideal conditions. Statistical parameters of nanoparticles are then analyzed using different data processing algorithms in order to show their systematic errors and to estimate uncertainties for atomic force microscopy analysis of nanoparticles under non-ideal conditions.

Different modeling conditions (coverage, relaxation after deposition) and convolution with different tip shapes are used to obtain a wide spectrum of virtual AFM nanoparticle images similar to those known from practice. In this article, we present a simple model for realistic simulations of nanoparticle deposition and we employ this model for modeling nanoparticles on rough substrates. However, in real situations, we often need to analyze nanoparticles on rough substrates or nanoparticles that are not isolated. For isolated nanoparticles on flat substrates, this is a relatively easy task. Nanoparticles are often measured using atomic force microscopy or other scanning probe microscopy methods.
