3_01/2007Cover Picture: Massively Parallel Dip-Pen Nanolithography of Heterogeneous Supported Phospholipid Multilayer Patterns (Small 1/2007)

The cover picture illustrates the use of self-organizing phospholipids as an ink for massively parallel dip-pen nanolithography. With this constructive lithographic technique it is possible to build model lipid-membrane patterns with sub-micrometer line widths over square-centimeter surface areas. The ability to pattern and integrate different membrane components opens many new possibilities in the fabrication of model systems that seek to simulate the chemical and structural complexity of biological membranes. For more information, please read the Communication “Massively Parallel Dip-Pen Nanolithography of Heterogeneous Supported Phospholipid Multilayer Patterns” by S. Lenhert, C. A. Mirkin, and co-workers on page 71. (Jacob Ciszek and Matthew Banholzer are gratefully acknowledged for the three-dimensional schematic in the cover picture.)
