A principal design of a single-beam optical trap is proposed based on the planar metalens assembled from an ordered array of dielectric microspheres arranged in a closely packed micro-assembly with a hollow center. By means of FDTD numerical simulation, we study in the detail the spatial structure of the optical field within the trap active zone and present an example of metalens-trap operation demonstrating the capturing and propulsion of a glass nanoparticle by the optical field.
