Chemical Patterning and Physical Refinement of Reactive Superhydrophobic Surfaces

An approach to the modification and post-fabrication chemical patterning of amine-reactive superhydrophobic surfaces is reported. The approach is based on the layer-by-layer fabrication of azlactone-containing polymer multilayers, and permits the direct covalent attachment and subsequent patterning of chemical and biological "inks" using a variety of pratical and low-cost pattern-transfer methods.
