The condensation of a liquid meniscus between a curved tip and a completely wetting substrate was studied in the context of dip-pen nanolithography (DPN). Using the Monte Carlo simulations of a two-dimensional lattice gas model the onset and the broadening of menisci by tips with a range of curvatures was studied. The tip-liquid interaction was characterized in terms of the wettability of the tip, and both wetting and drying tips were considered to mimic the various ink molecule-water interactions possible in DPN.
