Abstract

We have fabricated entirely by femtosecond micromachining a plastic optofluidic chip with integrated microfluidics and optical excitation/detection. First a microfluidic channel and two fiber grooves were ablated on one surface of the PMMA substrate. In order to collect and focus the fluorescence signal onto a detector, two binary Fresnel lenses were micromachined on the back surface of the substrate. The operatio of the integrated optofluidic chip was demonstrated by filling the channel with different Rhodamine 6G solution, and a limit of detection of 50 nM was achieved.
