Microcontact chemistry: surface reactions in nanoscale confinement — •Bart Jan Ravoo — Organic Chemistry Institute, Westfälische Wilhelms-Universität Münster, Corrensstraße 40, 48149 Münster, Germany

Microcontact printing is an established method for the preparation of physical, chemical and biological patterns on solid surfaces. Typically, microcontact printing involves a microstructured elastomer stamp that delivers a molecular ink in the contact area between stamp and substrate. Recently, it has been shown that microcontact printing can also induce chemical reactions when an ink is printed on a substrate, even when the reaction partners are normally unreactive. Rapid and spatially controlled surface reactions induced by microcontact printing enable the molecular modification and patterning of a wide range of inorganic and organic substrates. This lecture will highlight our newest findings concerning the scope and kinetics of surface chemistry by microcontact printing as well as its application in bionanotechnology.
