Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201304589-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>A simple method for fabricating high‐aspect‐ratio</bold>, hierarchical, and dynamically tunable surface patterns is invented by harnessing localized‐ridge instabilities in gold nanofilms coated on elastomer substrates (a); a theoretical model to calculate the critical parameters (e.g., wavelength and amplitude) for designing the new patterns is developed (b); and novel applications of the patterns as super‐hydrophobic coatings (c) and biomimetic cell‐culture substrates (d) capable of on‐demand tunability are demonstrated. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg4sr6pn6p" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
