  1. 1. Optical manipulation and heating of gold nanoparticles near interfaces

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Daniel Andrén; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LSPR spectroscopy; particle-surface separation distance; thermal reshaping; TIRM; nanomotor; plasmonics; photothermal effects; Brownian dynamics; gold nanorod; optical tweezers;

    Abstract : By focusing laser light to small volumes, its momentum can be used to trap and manipulate objects in the size range from cells down to single atoms. Devices using this effect are called optical tweezers, and have found use in measuring and applying minuscule forces and torques, contributed to deepening our knowledge of molecular motors, unraveling the mechanics of cells and DNA, and better understand statistical mechanics and hydrodynamic interactions at the nanoscale.
