Abstract

Tailored hydrophobic and oleophobic surfaces are exploited for controlling the wetting behaviour and evaporation process of solution dropped on them. This enables molecules and nano-objects that are dissolved in water or organic solvents to be delivered and arranged in a well-defined 2D layout.

Keywords: plasmonic sensors; self-assembly; super-hydrophobic surfaces; super-oleophobic surfaces; wettability.
