Joint CeNS Colloquium with SFB1032
Title: Single Molecules on Optical Whispering Gallery Modes
Host: Prof. Thorben Cordes, Prof. Don Lamb, Prof. Philip Tinnefeld
Summary: Optoplasmonic microcavities based on whispering-gallery modes are sensors developed in the past decade that combine the high quality factors of dielectric microcavities and the small nanometer-scale localization of electric fields by metal nanoparticles to achieve exceptional sensitivity for detecting single molecules in solution. These sensors have enabled the detection of single ions, enzyme activity and various ligand reactions/interactions. I will describes the photonic working principle of these sensors with a focus on the experimental aspects.
