Ink Diffusion in Dip-Pen Nanolithography: A Study in the Development of Nano Fountain ProbesPublic Deposited
The intention of this research was to investigate the ink diffusion that takes place in dip-pen nanolithography in order to better understand how to enhance the possibilities of nano fountain probes. Varying concentrations of 16-mercaptohexadecanoic acid in ethanol were used as ink in dip-pen nanolithography, and the relationships between contact time, concentration, and ink diffusion were studied. It was found that for all concentrations, ink diffusion showed a dependence on contact time, but some concentrations showed a stronger dependence than others. After comparing results across different concentrations, it was also shown that there is a specific, nonlinear relationship between ink diffusion and concentration. In addition, it was shown that dip-pen nanolithography has limitations in multipletrial studies. Further investigation could indicate which inks are most appropriate for nano fountain probes.
