Abstract
We present a simple bottom-up colloidal route towards the manufacture of hierarchical substrates. Owing to the double length scale roughness, these super-structure arrays exhibit superhydrophobic wetting behaviour, characterized by large contact angles, limited hysteresis and small sliding angles. The assembly procedure of the nanocolloidal silica and gold particles is reviewed, as well as the chemical treatments required to obtain stable, reproducible substrates
