Water drops used as reaction compartments are commonly immobilized on hydrophilic areas bordered by hydrophobic areas. For many applications, such as the trapping of non-adherent cells, it is desirable to exploit the inertness and the anti-fouling behavior of hydrophobic surfaces as well as their repulsive behavior towards adsorbates in lab-on-chip configurations. However, the immobilization of water drops on hydrophobic surfaces has remained challenging. We report a nonlithographic approach to… Expand

Nanostructured Submicron Block Copolymer Dots by Sacrificial Stamping: A Potential Preconcentration Platform for Locally Resolved Sensing, Chemistry, and Cellular Interactions
Classical contact lithography involves patterning of surfaces by embossing or by transfer of ink. We report direct lithographic transfer of parts of sacrificial stamps onto counterpart surfaces.Expand
The Influence of Surface Topography and Surface Chemistry on the Anti-Adhesive Performance of Nanoporous Monoliths.
The design of spongy monoliths allowing liquid delivery to their surfaces through continuous nanopore systems may pave the way for the design of artificial surfaces with tailored contact mechanics, and the results reported here may contribute to better understanding of the contact mechanics of biological surfaces.

Reversible adhesion switching of porous fibrillar adhesive pads by humidity.
Reversible adhesion switching on porous fibrillar polystyrene-block-poly(2-vinyl pyridine) (PS-b-P2VP) adhesive pads by humidity changes is reported, with main origin of enhanced adhesion at high humidity is the humidity-induced decrease in the elastic modulus of the polar component P2VP rather than capillary force.

Spatial Control of Condensation on Chemically Homogeneous Pillar-Built Surfaces.
This work exploits a phenomenon where the water vapor flux is focused on the apexes of surface asperities by diffusion while matching the nucleation point density to the array dimensions to obtain a perfect droplet array. Expand
Binary DNA arrays on heterogeneous patterned surfaces
Studies of the deoxyribonucleic acid (DNA) molecule at surfaces are driven by both the inherent interest in understanding different aspects of this molecule and its importance in biomimetic materialsExpand

Non-sticking drops
While the behaviour of large amounts of liquid is dictated by gravity, surface forces become dominant at small scales. They have for example the remarkable ability to make droplets stick to theirExpand
Questions and Answers on the Wettability of Nano‐Engineered Surfaces
Surface roughening has long been used to confer materials remarkable wetting properties, such as super hydrophobicity. When roughness belongs to the microscale, existing models can, to some extent,Expand
Mesoporous block copolymer nanorods by swelling-induced morphology reconstruction.
It is shown that swelling-induced structural transitions in nanorods consisting of amphiphilic BCPs involve pronounced reshaping of the nonswollen glassy domains in the course of the transition from the equilibrium morphology of the molten BCP in cylindrical confinement to that of the BCP dissolved in the swelling agent.

Wetting and Roughness
We discuss in this review how the roughness of a solid impacts its wettability. We see in particular that both the apparent contact angle and the contact angle hysteresis can be dramatically affectedExpand
