Abstract

In this work, we demonstrate an original single-nanoparticle deposition process based on near-field optical forces arising from much localized plasmonic resonant gap-mode. At first, nanoparticles exclusively made of fluorescent dye molecules are fabricated in aqueous colloidal suspension. Near-field optical forces are then used to attract and deposit single nanoparticles in the nanogap of plasmonic nanoantennas. This one-step deposition process allows targeted deposition of nanoscale materials directly from a colloidal dispersion to a few-nanometer large area of interest.
