Abstract

In this work the combined use of direct laser writing (DWL) and a new epoxy material (mr-DWL) for fast prototyping of μTAS devices is demonstrated. The fabrication process is based in the use of DWL to manufacture epoxy-based masters without using any mask, and replicate them into PDMS. A total processing time of less than 12h from the design to the final working μTAS is demonstrated. Two different PDMS microfluidic structures are fabricated and tested as proof of concept of the good performance of the proposed technology.
