    "abstract": "We propose a novel way to trap and manipulate nano-objects above a dielectric\nsubstrate using an apertureless near-field probe. A combination of evanescent\nillumination and light scattering at the probe apex is used to shape the\noptical field into a localized, three dimensional optical trap. We use the\ncoupled-dipole method and the Maxwell stress tensor to provide a\nself-consistent description of the optical force, including retardation and the\ninfluence of the substrate. We show that small objects can be selectively\ncaptured and manipulated under realistic conditions.",
