The first grand canonical Monte Carlo (GCMC) calculation of the capillary force for a nanoscale tip interacting with a flat surface is presented. To examine both hydrophilic and hydrophobic tip such as are used in dip-pen nanolithography (DPN), tips with different wettabilities are simulated. Based on a two-dimensional lattice gas model, the capillary force is studied by systematically varying the tip-substrate distance and saturation.
