Elastomeric Molds with tunable microtopography

Elastomeric microtunable molds (muTMs) whose microtopography can be tuned post-fabrication at certain pre-defined locations have been devised. Their features make them very attractive for the molding of complex microstructures. The Figure shows a scanning electron microscopy image of poly(dimethylsiloxane) double-replicas of a muTM whose membrane contains a 1.18 mm spiral.
