A diffusive ink transport model for lipid dip-pen nanolithography.
Despite diverse applications, phospholipid membrane stacks generated by dip-pen nanolithography (DPN) still lack a thorough and systematic characterization that elucidates the whole ink transport process from writing to surface spreading, with the aim of better controlling the resulting feature size and resolution. We report a quantitative analysis and modeling of the dependence of lipid DPN fe...
متن کاملOptimizing microfluidic ink delivery for dip pen nanolithography
Joe Fragala NanoInk Inc. Microfabrication Group Campbell, California 95008 Abstract. In Dip Pen NanolithographyTM (DPNTM) ultrasharp tips coated with chemical compounds (or ‘‘ink’’) are in contact with a surface to produce submicron sized features. There is a need to deliver multiple inks to an array of closely spaced tips (or ‘‘pens’’). This work demonstrates the design optimization, fabricati...
متن کامل"Dip-Pen" nanolithography
A direct-write "dip-pen" nanolithography (DPN) has been developed to deliver collections of molecules in a positive printing mode. An atomic force microscope (AFM) tip is used to write alkanethiols with 30-nanometer linewidth resolution on a gold thin film in a manner analogous to that of a dip pen. Molecules are delivered from the AFM tip to a solid substrate of interest via capillary transpor...
متن کاملThe role of viscosity on polymer ink transport in dip-pen nanolithography.
Understanding how ink transfers to a surface in dip-pen nanolithography (DPN) is crucial for designing new ink materials and developing the processes to pattern them. Herein, we investigate the transport of block copolymer inks with varying viscosities, from an atomic force microscope (AFM) tip to a substrate. The size of the patterned block copolymer features was determined to increase with dw...
متن کاملElectrochemical AFM "dip-pen" nanolithography.
In recent years, SPM-based lithography has attracted great attention because of its simplicity and precise control of the structure and location. Many SPM lithography techniques based on mechanical scratching,1 anodization of Si surfaces,2 electrochemical decomposition of self-assembled monolayers,3 electric field-induced chemical reactions,4 electrochemical reactions in solution using electroc...
