Microfluidic patterns of 100 lm in width and 50 lm height were replicated from a master using vacuum casting with silicone rubber. These silicone copies are subjected to thorough analysis for dimensional accuracy against the master pattern. Analysis of experimental results shows repeatability of the silicone rubber molds. To test the limits of vacuum casting with silicone rubber, an attempt was undertaken to replicate 8 lm microchannel and submicron features. The results show that casting of microfluidic channel via vacuum casting has high repeatability.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
