Paper Abstract

In Dip Pen Nanolithography® (DPN®), ink transport is reported to occur through the water meniscus formed between the AFM tip and the substrate by capillary condensation. It is imperative to understand the ink transport mechanisms in order to develop reliable commercial applications of DPN, and NanoInk is at the forefront of these efforts. In this work, we model the dot patterns of 16-Mercaptohexadecanoic acid (MHA) created by evaporative coating of a 1D 18 cantilever array and perform predictive modeling with solution based MHA cantilever inking results. We extend the functionality of the NanoInk 2D nano PrintArrayTM (2D array) by measuring the uniformity of 1-octadenethiol (ODT) dot patterns created. Further, we try to quantify the uniformity of patterns created by the 2D array, in a more statistically quantitative way. We do this by measuring the dot diameters of over 200 ODT ink patterns over a 1x1cm2 area and examining the uniformity of the ODT vapor inking protocol developed.
