Combinatorial Analysis of Functional Interfaces and Surfaces Generated Via Dip-Pen Nanolithography
Abstract
The effect of an organic solvent atmosphere on ink deposition and deposition transport rate was studied and quantified. Various chemical compounds spanning a range of hydrophobicities and meniscus solubilities were used as inks in DPN and deposited in a variety of solvent atmospheres such as ethanol, methanol, hexanes and methylene chloride. The data obtained in these experiments will improve our understanding of the factors that govern the rate of ink delivery from tip to substrate, especially for air or water sensitive adsorbates. Another interesting outcome of these studies was the observation that introduction of an organic solvent into an inert atmosphere will increase the diffusion rate of certain alkanethiols by orders of magnitude and hence increase the deposition rate of these materials onto solid surfaces. These studies are in the process of being written up for publication, and submission to Langmuir is planned.
