Detection and sizing of standard PS nanoparticles. (a) Normalized transmission power when single nanoparticles with a diameter of 130 nm attached to the waveguide (d~350 nm). The red dashed curve is plotted to guide the eye. (b) Statistical analysis for scattering efficiencies induced by PS nanoparticles with a single diameter of 90 nm using the same nanowaveguide when the probe light is circularly (top panel) and linearly (bottom panel) polarized. Red curves show the Gaussian fitting. (c) Statistical analysis for nanoparticle sizes with diameters of 100, 130 and 200 nm using circularly polarized probe light.
