    We use frequency-locked microtoroid optical resonators to detect protein biomarkers at attomolar to femtomolar concentrations depending on the target. We validate these results against existing sensing technologies. In addition, we present new designs to further improve our sensing platform, including alternative light coupling strategies based on plasmonic nanoparticles for increased portability and new hybrid-microcavity designs for enhanced sensitivity. We anticipate that these designs will enable ultra-sensitive, rapid, selective, and portable diagnostics. In addition, we believe that our results demonstrating detection in real patient samples constitute a significant step forward in the optical whispering gallery mode biosensing field.
