  • Abstract
    We report a method of characterising physical and optical properties of nanoparticles using optical tweezers combined with dark field microscopy. The technique uses measurements from Brownian dynamics of the trapped nanoparticles to determine localised surface plasmon resonance (LSPR) spectroscopy to determine nanoparticle size information.
