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.
