Dual-polarization optofluidic biodetection based on polymer microring resonators

We previously demonstrated that vertically-coupled polymer microring resonators are good candidates as transducers in label-free biosensing instruments, for several reasons: good optical performances, low production costs, excellent biocompatibility and state-of-the-art surface sensitivity. We later presented the association of our original opto-electronic setup to microfluidics to perform homogeneous optofluidic detection, using glucose solutions to characterize the behavior of the microring transducer. In parallel, the same transducer devices have been associated to another detection scheme, phase-sensitive OLCI, with promising results.
