Abstract :
Miniaturized optofluidic systems with integrated waveguides and microfluidic channels were built as monolithic polymer devices. Their potential for biosensor applications was demonstrated by two examples: (1) Change of the light attenuation as function of the analytepsilas refractive index, (2) Channels functionalized by Dip-Pen Nanolithography allowed the selective capture of fluorescent markers, which were detected after local excitation through the waveguides.
