Abstract

We demonstrate, for the first time, 2-dimensional (2D) direct print of perfect circle microdots consisting of close-packed Au nanoparticles by employing the optical vortex induced forward transfer (OV-LIFT). Going beyond the ink-jet printing technology, the OV-LIFT allows the direct print of ultrafine microdots with a diameter of ~8 μm and an ultralow positional error of <7 μm.
