Miniaturized sensors mounted upon optical fibers are widely recognized as an important future solution to instant and point-of-care medical diagnosis and on-site agricultural produce inspection. Plasmonic devices on the flat end-facets of single-mode fibers use fiber-optic devices’ convenient and rapid operation capabilities to the fullest. They can be directly dipped into minute samples or inserted with minimal invasion.
