Applications of dip-pen nanolithography Nature
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, … See more Direct write DPN is a direct write technique so it can be used for top-down and bottom-up lithography … 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 pyramid, leaving an aperture for light to pass through. The array is then scanned across a … See more Molecular inks Molecular inks are typically composed of small molecules that are coated onto a DPN tip and are … See more A heated probe tip version of Dip Pen Lithography has also been demonstrated, thermal Dip Pen Lithography (tDPL), to deposit nanoparticles. Semiconductor, magnetic, metallic, or optically active nanoparticles can be written to a substrate via this method. … See more Direct comparisons to other techniques The criticism most often directed at DPN is the patterning speed.
