Dip pen nanolithography (DPN) is a scanning probe lithography technique where an atomic force microscope (AFM) tip is used to directly create patterns on a substrate. [1] It can be done 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 surface ...
Dip-pen scanning probe lithography (dp-SPL) or dip-pen nanolithography (DPN) is a scanning probe lithography technique based on diffusion, where the tip is employed to create patterns on a range of substances by deposition of a variety of liquid inks.
Some of the important techniques in this category include dip-pen nanolithography, thermochemical nanolithography, thermal scanning probe lithography, and local oxidation nanolithography. Dip-pen nanolithography is the most widely used of these techniques. [8]
Related fields are thermo-mechanical SPL (see also Millipede memory), thermochemical SPL [2] [3] (or thermochemical nanolithography) where the goal is to influence the local chemistry, and thermal dip-pen lithography [4] as an additive technique.
The advent of dip-pen nanolithography (DPN) in recent years represented a revolution in nanoscale patterning technology. With sub-100-nanometer resolution and an architecture conducive to massive parallelization, DPN is capable of producing large arrays of nanoscale features.
