✦ Synopsis

Massively parallel dip–pen nanolithography is possible when 55 000 AFM cantilevers are used to write molecules directly onto a surface. An optical micrograph shows the surface after etching (cover picture, left), and each round feature is a miniature image of the face of Thomas Jefferson (AFM image, right), who helped develop the polygraph, a duplicator based on an array of pens. For more information on the new technique see the Communication by C. A. Mirkin and co‐workers on page 7220 ff.
