Gold threads modified with superhydrophobic or normal hydrophobic coatings are used as a model system in the study of the contribution of the superhydrophobic coating of a water strider to its floating and movement on the water surface. After depositing Pt aggregates on one of its ends (see figure), the gold threads are able to move in the H 2 O 2 aqueous solution. The superhydrophobic coating decreases fluidic drag during motion.
