    • Scanning electron microscopy indicates a fairly spherical shape of the Au nanoparticles (≈7nm radius) with <20% size distribution. The plasmon resonance of these particles in air is near 510 nm.

    • From transmission electron microscopy studies, the last 200 nm of the probe is conical with a half angle of (10°-11°) and a 3-5 nm radius.

    • note
    • The AFM scan reflects a constant vertical force gradient, which could be subtly different for Si-quartz than for Si-Au. However, based on the known distance to the surface (≈2.5nm) and based on a simple Lennard-Jones pair potential, one can estimate that these differences do not affect the AFM scans significantly.
