Photonic structures coupled to single quantum emitters are key elements for integrated quantum technologies. Up to now, a reliable method to couple theses elements is the main challenge of their fabrication. We present a method where long-range electrostatic forces between an atomic force microscope (AFM) tip carrying a nano particle hosting a single photon emitter (SPE), and the target surface are induced. This allows for positioning of SPEs on non-transparent conductive samples with sub-micrometer precision in non contact mode. The placement site can be identified with sub micrometer precision without any tip approach, eliminating the risk of a particle loss. We demonstrate the strength of the method by transferring a nanometer sized diamond containing a single nitrogen-vacancy defect to the center of a micrometer-sized silver bullseye antenna with nanometer resolution. Our approach provides a simple and reliable assembling technology for positioning single nano objects on opaque substrates with high reproducibility and precision.
