In this presentation, we will report on advancing chip-scale biosensing capabilities with optical microresonators. His laboratory has developed a microcavity biosensing platform that is capable of monitoring single DNA molecules and their interaction kinetics, hence achieving an unprecedented sensitivity for label-free detection with light. By thermal stabilization of the sensor it is furthermore possible to characterize the structural change of biopolymers in response to temperature. Stand-off biodetection capabilities are demonstrated with asymmetric microspheres.
