Abstract
We propose a novel way to trap and manipulate nano-objects above a dielectric substrate using an apertureless near-field probe. A combination of evanescent illumination and light scatterig at the probe apex is used to shape the optical fields into a localized, three dimensional optical trap. We use the coupled-dipole method and the Maxwell stress tensor to provide a self-consistent description of the optical force, including retardation and the influence of the substrate, and we show that under realistic conditions, small objects can be selectively captured and manipulated under realistic conditions.Citation
