Model Topographies

A well characterized microtopography is essential for all scientific research involving surfaces and interfaces. Most surfaces present features on multiple length scales making it hard to isolate the effect of the macro, micro, or nano scale on a test result.
micropat SA drastically simplifies this problematic through “ideal” periodic micropatterned topographies. These surfaces are “ideal” in the sense they can be described by one characteristic length scale and present a negligible nanoroughness.
A set of such surfaces allows to vary an interaction size while keeping one machining technique and hence a constant nanorougness and surface chemistry.
