Paper Abstract

We have used an embossed plastic microfluidic system for the electrophoretic separation of relatively small molecules followed by electro spray ionization of the analytes. Th separation of dyes has been also visualized in microfluidic systems. A lithographically produced silicon master was used to emboss channels in ZEONOR 1020R plastic. An oxygen plasma was used to convert the plastic channel surface from hydrophobic to hydrophilic characteristics for the separation of molecules in aqueous solution.
