Abstract

Due to their low cost compatibility with replication-based fabrication methods, thermoplastics represent an exceptionally attractive family of materials for the fabrication of lab-on-A-chip platforms. A diverse range of thermoplastic materials suitable for micro fluidic fabrication is available, offering a wide selection of mechanical and chemical properties that can be leveraged and further tailored for speci fi c applications. While highthroughput embossing methods such as reel-To-reel processing of thermoplastics is an attractive method for industrial micro fluidic chip production, the use of single chip hot embossing is a cost-effective technique for realizing high-quality micro fluidic devices during the prototyping stage. Here we describe methods for the replication of microscale features in two thermoplastics, polymethylmethacrylate (PMMA) and polycarbonate (PC), using hot embossing from a silicon template fabricated by deep reactive-ion etching.
