Microfluidic devices made of UV-curable glue (NOA81) for fluorescence detection based applications

The UV-curable adhesive NOA81 (Norland Optical Adhesive) is a promising liquid photopolymer for low-cost microfluidic chip production. Different fabrication methods for NOA81 are suggested [1,2]. However, optical characterization for fluorescent based detection systems is missing. We present a comparison of fluorescent emissionspectra of various NOA types as well as the time evolution of the spectra of the most promising one - NOA81. We report on a simple rapid prototyping technique to produce chips for fluorescent based capillary electrophoresis (CE). As an application, we show the CE-injection of a fluorescent dye, and its detection by fluorescence microscopy.
