Dewetting of poly(lactic-co-glycolic acid) fi lms is a new versa-tile method for designing breath fi gure structures on nanoscale rate. Most of the techniques known for the construction of nanostructured surfaces can only be applied for coating very small areas; however, the method presented by Eyas Dayyoub et al. (pp. 1279–1283) has high potential for patterning fi lms without limitation of the surface size. Variations of dewetting parameters lead to different pore sizes and surface roughness. Adhesion of bacteria (i.e., Escherichia coli) on various surfaces was investigated to determine the infl uence of such structures on bacteria behav-iour. The surface with the largest pore size (about 500 nm on aver-age) showed the highest anti-adhesive properties. Decreasing the pore sizes to below 500 nm reduced the anti-adhesive properties of the fi lms. Unstructured PLGA fi lms, prepared by the spin-coating method, exhibited the lowest anti-adhesive properties. These fi nd-ings show how the bacterial adhesion can be controlled by fi lm structuring. On the Front Cover, a nanostructured poly(lactic-co-glycolic acid) fi lm prepared by the dewetting method is displayed.

FRONT COVER

Page 1215 _____________ Recent and forthcoming publications in pss

BACK COVERAs shown by Boarino et al. (pp. 1412–1416), an array of silicon nanowires can be obtained by the self-assembly of polystyrene nanospheres and metal assisted etching. A thin fi lm of noble metal like silver or gold is nano-indented by sputter etching of Ar+ ions through the interstitial voids among the hexagonal close-packed assembly of the spheres. During the successive metal assisted etching, the thin metal fi lm sinks into the bulk of silicon extruding ordered silicon nanowires.
