Abstract
A microfluidic device having durable anisotropic wetting fluid contact surfaces in the fluid flow channels of the device. The anisotropic wetting surface generally includes a substrate portion with a multiplicity of projecting regularly shaped microscale or nanoscale asperities disposed in a regular array on the surface. Each asperity has a first asperity rise angle and a second asperity rise angle relative to the substrate. The asperities are structured to meet a desired retentive force ratio (f.sub.1/f.sub.2) caused by asymmetry between the first asperity rise angle and the second asperity rise angle according to the formula: f.sub.1/f.sub.2=(.omega..sub.1+1/2.DELTA..theta..sub.0)/sin(.ome-ga..sub.2+1/2.DELTA..theta..sub.0), .DELTA..theta..sub.0=(.theta..sub.a,0-.theta..sub.r,0).
