The cover picture illustrates the concept of multiplexed dip-pen nanolithography, where different tips in a parallel array simultaneously integrate materials on the same surface with both high resolution and throughput. Inkjet printing is used to deliver the different inks to different tips in the arrays for large-scale integration, while the use of lipid inks enables the incorporation of functional biomolecules. A schematic image of the concept is shown along with fluorescence micrographs of multicomponent phospholipid patterns fabricated by this technique. For more information, please read the Communication “A Self-Correcting Inking Strategy for Cantilever Arrays Addressed by an Inkjet Printer and Used for Dip-Pen Nanolithography” by C. A. Mirkin et al. and Full Paper “Multiplexed Lipid Dip-Pen Nanolithography on Subcellular Scales for the Templating of Functional Proteins and Cell Culture” by S. Lenhert et al., beginning on pages 1666 and 1785, respectively.
