Abstract
UV excimer laser photoablation was used to micro-machine polymer substrates not only to drill microchannel structures but also to change the surface physical properties of the substrates. We first describe how UV laser photoablation can be used for the patterning of biomolecules on a polymer and discuss parameters such as surface coverage of active antibodies and equilibration time. Secondly, we show how to design a single-use capillary electrophoresis system comprising an on-chip injector, column and electrochemical detector. The potential of this disposable plastic device is discussed and briefly compared to classical systems. Finally, preliminary results on protein separation by isoelectric focusing on a disposable microchip are presented.
