Scanning aperture trapping of nanoparticles for plasmonic enhancement of fluorescence — •Yazgan Tuna, Ji Tae Kim, and Vahid Sandoghdar — Max-Planck-Institute for the Science of Light, 91058 Erlangen

Trapping and manipulation of small objects have been of interest for a range of applications. Here we report on an electrostatic trap that is created in an aqueous medium between the aperture of a nanopipette and a glass substrate without the need for external potentials. Furthermore, we demonstrate scanning aperture trapping and manipulation of nanoparticles and study the plasmonic enhancement of fluorescence of a single fluorophore.
