Thin films of dry gelatin doped with potassium hexacyanoferrate are chemically micropatterned with a solution of silver nitrate delivered from an agarose stamp. Precipitation reaction between the two salts causes the surface to deform. The mechanism of surface deformation is shown to involve a sequence of reactions, diffusion, and gel swelling/contraction. This mechanism is established experimentally and provides a basis of a theoretical lattice-gas model that allows prediction surface topographies emerging from arbitrary geometries of the stamped features. The usefulness of the technique is demonstrated by using it to rapidly prepare two types of mold for passive microfluidic mixers.","lang":"eng"}],"issue":"1","date_published":"2005-01-21T00:00:00Z","extern":"1","publication_status":"published","pmid":1,"date_updated":"2023-08-08T12:15:48Z","month":"01","article_processing_charge":"No","day":"21","type":"journal_article"}
