Electrochemical AFM “Dip-Pen” Nanolithography

The development of nanometer-scale lithographies is the focus of an intense research activity because progress on nanotechnology depends on the capability to fabricate, position and interconnect nanometer-scale structures. The unique imaging and manipulation properties of atomic force microscopes have prompted the emergence of several scanning probe-based nanolithographies. In this tutorial review we present the most promising probe-based nanolithographies that are based on the spatial confinement of a chemical reaction within a nanometer-size region of the sample surface. The potential of local chemical nanolithography in nanometer-scale science and technology is illustrated by describing a range of applications such as the fabrication of conjugated molecular wires, optical microlenses, complex quantum devices or tailored chemical surfaces for controlling biorecognition processes.

“…DPN is compatible with many inks, from small organic molecules [1][2][3][4][5][6][7][109][110][111] to organic [8][9][10] and biological [11,12] polymers (Figure 2 C, D), and from colloidal particles [13,31,65] to metal ions [14][15][16] and sols. [17,18,112] DPN can be used to pattern surfaces ranging from metals to insulators and to pattern on top of functional monolayers adsorbed on a variety of surfaces.…”

“…[65] In another direct-patterning approach for hard-nanostructure fabrication, J. Liu and co-workers have used both electrochemical and electroless versions of DPN to deposit metal nanostructures on surfaces. [14,15] By using the water meniscus not only as a transport medium, but also as a nanoscale electrochemical cell, they were able to deposit Pt, Au, Ge, Ag, Cu, and Pd through electrochemical reduction onto a Si surface in a technique they termed E-DPN (electrochemical-DPN). [14] Significantly, they also showed that the deposited features were not the result of anodic oxidation of the Si, but rather arose from metal reduction.…”

“…An interesting alteration of DPN is to use the meniscus as an electrochemical cell, by applying a bias between the two, similar to the anodic oxidation described before. This electrochemical DPN technique can be used to fabricate metal and semiconductor nanostructures directly [57]. DPN can also be used for the creation of nanostructures on a surface for directed assembly of nanoparticles [58] (Figure 7).…”

-Manufacturing of nanomaterials is an interdisciplinary field covering physics, chemistry, biology, materials science and engineering. The interaction between scientists with different disciplines will undoubtedly lead to the production of novel materials with tailored properties. The success of nanomanufacturing depends on the strong cooperation between academia and industry in order to be informed about current needs and future challenges, to design products directly transferred into the industrial sector. It is of paramount importance the selection of the appropriate method combining synthesis of nanomaterials with required properties and limited impurities as well as scalability of the technique. Their industrial use faces many obstacles as there is no suitable regulatory framework and guidance on safety requirements; specific provisions have yet to be established in EU legislation. Moreover, regulations related to the right of intellectual properties as well as the absence of an appropriate framework for patent registration are issues delaying the process of products' industrial application. The utilization of high-quality nanomaterials is now growing and coming to the industrial arena rendering them as the next generation attractive resources with promising applications. Undoubtedly, the existing gap between basic research relating nanomaterials and their application in real life will be overcome in the coming decade.
