Nanoparticles (IMAGE) University of Copenhagen - Niels Bohr Institute Caption The experiments were carried out with nanoparticles of different sizes and structures. The first two of the series consisted of solid gold and the last consisted of a core of glass with a surface of gold. The beads were illuminated with near infrared light with wavelengths of 807 nanometers and 1064 nanometers. The most effect nanoparticle was the gold-plated glass bead.
