Fast prototyping of microfluidic devices for separation science

In recent years the field for miniaturised micro-fluidic devices such as miniaturised GC, HPLC, CE and CEC as well as micro-reactors and micro-mixers has grown rapidly. Therefore, technologies to build new devices faster and cheaper has become increasingly important. The classic production technique for glass or silicon is photolithography followed by wet etching. Major time and cost factors in this process are the production of lithography masks. A process to design masks based on printouts on office printers and photographic reduction was therefore developed.
