AFM is a mode of scanning probe microscopy.  In the AFM, the tip is mounted on a cantilever and the tip scanned the sample surface line by line, which is a raster scan.  Then a laser beam senses the deflection of the cantilever and the signal is detected.  The advantage of using the AFM is to provide measurements in three dimensions.  The results for the nanoparticles are not high quality, however it is seen that there are some particles with a height of 50 nm on the surface of the copper TEM grid.  The 3D image was fit to plane, but the TEM grid may not have been completely flat and smooth which means that the particle height is closer to 20-30 nm instead of 50 nm.
