An optofluidic hybrid platform based on hybrid liquid core ARROW waveguides has been fabricated and tested. Solid core hybrid ARROW was integrated in a self-aligned optical configuration with the ARROW optofluidic channel for an improved collection efficiency. The platform was fabricated using a modular approaches. The microfluidic system was completely realized with PDMS using a layered structure while the optical part was realized developing a hybrid silicon/PDMS solution. The performance of the system has been tested by carrying out fluorescence measurements on Cy5 water solutions, obtaining an LOD of 2.5 nM. © 2014 SPIE.
