Shifting molecular localization by plasmonic coupling in a single-molecule mirage

Over the last decade, two fields have dominated the attention of sub-diffraction photonics research: Plasmonics and fluorescence nanoscopy. Nanoscopy based on single-molecule localization offers a practical way to explore plasmonic interactions with nanometre resolution. However, this seemingly stra...
