Table 1.

Four distinct topographic geometries were patterned via hot embossing to PCTE membranes. The geometries ranged from 0.5–1.0 μm ridge/groove features to 1.0 μm posts. All features were designed to be evenly spaced with a 1 : 1 ratio of feature width to spacing and to have a height of 0.75 μm. Non-embossed PCTE membranes served as control samples
