19_17b/2007Inside Front Cover: Towards Understanding Why a Superhydrophobic Coating Is Needed by Water Striders (Adv. Mater. 17/2007)

Gold threads modified with superhydrophobic or normal hydrophobic coatings are used as model system in the study of the contribution of a superhydrophobic coating of water striders to their floating and movement on water surfaces. After depositing Pt aggregates on one of its ends, the gold threads are able to move in the H2O2 aqueous solution. The superhydrophobic coating is proven to be able to decrease fluidic drag during motion, as described by Xi Zhang and co-workers on p. 2257.
