Stability of molded polydimethylsiloxane microstructures

Emmanuel Delamarche, Heinz Schmid, Bruno Michel, Hans A. Biebuyck

Abstract

How stable are the features in elastomeric stamps—as used in microcontact printing (μCP) and micromolding in capillaries (MIMIC)—during their formation and subsequent application? Their stability is examined with respect to aspect ration and forces during handling. In the Figure, lines in the structure (gold on silicon), produced using an elastomeric stamp, can be seen to have merged into larger ensembles. magnified image
