20_21b/2008Inside Front Cover: Versatile Approach for Integrative and Functionalized Tubes by Strain Engineering of Nanomembranes on Polymers (Adv. Mater. 21/2008)

A generic approach to engineering tubular micro-/nanostructures out of many different materials with tunable diameters and lengths by precisely releasing and rolling up functional nanomembranes on polymers is reported on p. 4085 by Yongfeng Mei and co-workers. This technology spans different scientific fields ranging from photonics to biophysics and optical ring resonators, magneto-fluidic sensors, remotely controlled microrockets (main image) and 2D confined channels (bottom right) for cell growth guiding are demonstrated.
