Dip-pen lithography
WebDip-Pen Nanolithography (DPN) DPN is the nanoscale equivalent of writing with a quill. In DPN, AFM probes are inked with a solution of molecules and then scanned along a surface to write a pattern of the ink. The ink solution forms a small meniscus between the tip of the probe and the surface, which transports biomolecules from the tip to the ... WebDip-pen nanolithography is used to directly modify freshly dissected eye tissues with biologically active collagen-binding peptide molecules. The results address the challenge of surface heterogeneity and utilize dip-pen nanolithography to control the localization and concentration of molecules on a collagen-terminated tissue-derived surface.

WebJan 5, 2024 · Dip-pen nanolithography (DPN) can directly write a variety of materials on the substrates at the sub-50 nm to micrometer length scale. While this tool has been extensively exploited to construct functional nanostructures and address important scientific questions, extending the capability from low-dimensional molecular patterning to direct … Mechanical scanning probe lithography (m-SPL) is a nanomachining or nano-scratching top-down approach without the application of heat. Thermo-mechanical SPL applies heat together with a mechanical force, e.g. indenting of polymers in the Millipede memory. Thermal scanning probe lithography (t-SPL) uses a heatable scanning probe in order to efficiently remove material from a surface without the application of significant mechanical forces. The patt…
