Cover Picture: Two-Component Graded Deposition of Biomolecules with a Double-Barreled Nanopipette (Angew. Chem. Int. Ed. 42/2005)

44_42/2005The persistence of Edgar Degas is illustrated in the formation of highly complex, graded, ‘two-color’ images on the submicron scale. Two species can be delivered independently from a single pipette through the use of scanning ion-conductance distance control. The cover picture shows biological molecules being delivered in air through a liquid meniscus at the tip of a double-barreled nanopipette (Salvador Dali, not to scale, is shown painting the Degas Dancers with a nanopipette) as described by D. Klenerman et al. in their Communication on page 6854 ff.
