21_18b/2009Superhydrophobic Coatings: Bioinspired Degradable Substrates with Extreme Wettability Properties (Adv. Mater. 18/2009)

João Mano and co-workers have developed new superhydrophobic poly(L-lactic acid) substrates for biomedical applications, reported on p.1830. The wettability of the substrates can be controlled within the superhydrophobic–superhydrophilic range by using argon plasma treatment. The inside cover image shows the texture of such a substrate exhibiting micro-and nanoscale roughness, which gives rise its extreme wettability behavior (the structure in the image can be viewed more clearly using 3D glasses).
