Claim:
1. A method of controlling wettability of a surface of an article, the method comprising: forming an array of nano-structures on the surface, the nano-structures providing a nano-structured surface with a modified wettability characteristic, wherein forming the array of nano-structures on the surface includes: applying a thin-layer surface coating onto the nano-pillar array to tune wettability of the nano-structured surface from the modified wettabilty characteristic toward a target wettability characteristic, wherein applying the thin-layer surface coating includes forming a first layer on the nano-pillar array, and forming a second layer on the first layer, the first layer being configured to chemically bond the second layer to the nano-pillar array, the second layer being a self-assembled monolayer; wherein:
