Abstract

Elastomeric “microtunable” molds (μTMs) 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 μTM whose membrane contains a 1.18 mm spiral.
