Abstract :
A coupling between multimode polymer waveguides and microfluidic channels on a polymethylmethacrylate (PMMA) capillary electrophoresis (CE)-chip for optical analytical applications has been successfully realised. This technology allows the integration of polymer optical waveguides together with hermetically sealed fluidic channels. The microchannels and waveguides are made in PMMA by the approved hot-embossing technology. The technology developed for the fabrication of polymer waveguides on the microfluidic chip offers the possibility of great flexibility in the choice of core materials, design and alignment of the polymer waveguides. The integration of polymer waveguides on an analysis chip enables highly spatially resolved optical detection without the large and expensive conventionally used apparatus. The optical properties of the analytical system developed are verified by transmission and propagation loss measurements. The results of measurements prove the suitability of the presented device for optical applications between 440 and 800 nm. This was shown with absorbance measurements of the dye Sulfanilazochromotrop (SPADNS) within 50 (mu)m fluidic channels.
