Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201302678-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Spatial control over the surface chemistry of 3D organic–inorganic hybrid microscaffolds</bold> is achieved by a two‐photon‐triggered cycloaddition. Following a coating step with photoactivatable dienes via silanization, surface irradiation with a femtosecond‐pulsed laser in the presence of functional dienophiles enables a site‐selective alteration of the surface chemistry. Bioconjugation with fluorescent protein tags is employed to reveal the 3D molecular patterns. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg3v0wrn2q" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
