There is provided a substrate comprising an array of non-pillar-shaped nanoformations extending from the surface of the substrate and being arranged to form, between adjacent non-pillar-shaped nanoformations, longitudinally shaped nano-sized depression formations, said nanoformations and said depressions being selected to enable the surface of the substrate to exhibit a higher pinning force relative to the surface of a substrate with an array of pillar-shaped formations.
