Abstract:The fundamentals of atomic force microscopy (AFM) of hard colloidal particles are discussed. The idea of image modeling and deconvolution with the known AFM cantilever tip shape is described as well as a method for AFM tip calibration with the use of spherical colloidal particles. The algorithms and programs for AFM image modeling and experimental data analysis are presented together with exemplary analysis and possible applications. The difficulties of the method are discussed.
