Description:
We present a method for controlling the initiation and kinetics of polymer crystal growth using dip-pen nanolithography and an atomic force microscope tip coated with poly-dl-lysine hydrobromide. Triangular prisms of the polymer epitaxially grow on freshly cleaved mica substrates, and their in-plane and out-of-plane growth rates can be controlled by raster scanning the coated tip across the substrate. Atomic force microscope images were concomitantly recorded, providing a set of photographic images of the process as it spans the nanometer- to micrometer-length scales as a function of environmental conditions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Xiaogang -- Zhang, Yi -- Goswami, Dipak K -- Okasinski, John S -- Salaita, Khalid -- Sun, Peng -- Bedzyk, Michael J -- Mirkin, Chad A -- GM62109-02/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2005 Mar 18;307(5716):1763-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Institute for Nanotechnology, Northwestern University, Evanston, IL 60208, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15774755" target="_blank"〉PubMed〈/a〉
