In this work SnS nanoparticles capped with tri-n-octylphosphine oxide (TOPO) have been characterized by Peak Force AFM. The topography map clearly showed single nanoparticles with a size less than 5 nm and spherical shape. In the conductivity map it was possible to discern the same nanoparticles. The same nanoparticles have been measured also by Torsional Resonant TUNA AFM in order to compare it with Peak Force AFM. From this comparison it has been found that the conductivity of nanoparticles, even if they are capped with TOPO, can be measured by Peak Force AFM, a result that thus far has been difficult to achieve by other types of AFM.
