An all polymer optofluidic chip with integrated waveguides for biophotonics

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.
