Webdepositions of nanoarrays this new Dip Pen Nano-lithography-based instrument is the first system capable of fabrication of sub-micron features over large sub-strates. With a dynamic range of deposited feature sizes ranging from sub-100 nm to over 10 μm, the NLP 2000 system brings truly unique capabilities to the world of nanofabrication. Dip pen nanolithography (DPN) is a scanning probe lithography technique where an atomic force microscope (AFM) tip is used to create patterns directly on a range of substances with a variety of inks. A common example of this technique is exemplified by the use of alkane thiolates to imprint onto a gold … See more The uncontrollable transfer of a molecular 'ink' from a coated AFM tip to a substrate was first reported by Jaschke and Butt in 1995, but they erroneously concluded that alkanethiols could not be transferred to gold substrates to … See more In order to define a good DPN application, it is important to understand what DPN can do that other techniques can't. Direct-write techniques, like contact printing, can pattern multiple biological materials but it cannot create features with subcellular resolution. Many … See more Direct write DPN is a direct write technique so it can be used for top-down and bottom-up lithography applications. In top-down work, the tips are used to … See more A two dimensional array of (PDMS) deformable transparent pyramid shaped tips are coated with an opaque layer of metal. The metal is then removed from the very tip of the … See more Molecular inks Molecular inks are typically composed of small molecules that are coated onto a DPN tip and are delivered to the surface through a water meniscus. In order to coat the tips, one can either vapor coat the tip or dip the tips into a … See more A heated probe tip version of Dip Pen Lithography has also been demonstrated, thermal Dip Pen Lithography (tDPL), to deposit See more Direct comparisons to other techniques The criticism most often directed at DPN is the patterning speed. The reason for this has more to do with how it is compared to other techniques … See more
