Caption
a, Principle of structural plasmonic tweezers, the right thumbnails are the trapping results through profiled metallic structures on a glass prism and a bowtie aperture on tapered metal-coated optical fiber. b, Schematic of focused plasmonic trapping of metallic particles, and the right thumbnails are the patterns constructed by transporting particles to and trapping them at designated points. c, Perspectives on the future development of plasmonic optical tweezers, the upper subfigure depicts the physical mechanism and related phenomena of the nonlinear plasmon-matter interactions and the lower one prospects its application in intracellular detections.
