Silicon photonic microring resonator arrays for scalable and multiplexable bioanalysis

Abstract

Silicon photonic devices, such as SOI microring resonators, have optical properties that are incredibly responsive to changes in the local dielectric environment accompanying a biological binding event at or near the ring surface. We have developed a platform in which arrays of uniquely addressable microrings are functionalized with target-specific capture agents so as to create a powerful tool for multiplexed biomolecular detection. We will discuss applications of this technology to the multiplexed detection of DNA, RNA, and proteins in clinically-relevant matrices, and will also describe the rigorous empirical determination of key sensitivity metrics.
