Màster en Nanociència i NanotecnologiaA rapid and cheap method has been developed for the
fabrication of a capillary electrophoresis chip for the
preliminary characterization of particles. The microfluidic
chips were fabricated using polymethyl methacrylate
(PMMA) with integrated platinum electrodes without the
need of using high technology microfabrication techniques.
The chips were characterized using electroosmotic flow
(EOF) with different channel treatments. The electrodes
were characterised with impedance and conductivity
measurements using both static and electrophoretic flow,
respectively. Nine micron diameter particles were detected
and their electrophoretic mobility determined using
capillary electrophoresis and conductivity detection
