Abstract

We present sequential trapping and positioning of 20 nm polystyrene particles into an array configuration by using metamaterial plasmonic tweezers. The polystyrene nanoparticles suspended into a heavy water solution were trapped on adjacent plasmonic hotspots with a very low excitation power of 3.8 mW, creating a large trap stiffness of about 3.5 fN/nm. This high trapping stiffness kept the particles trapped into the nanocavities’ hotspots achieving almost 80% occupancy of the excited hotspots.
