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

    Författare :Daniel Andrén; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LSPR spectroscopy; particle-surface separation distance; thermal reshaping; TIRM; nanomotor; plasmonics; photothermal effects; Brownian dynamics; gold nanorod; optical tweezers;

    Sammanfattning : 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.

  3. 2. Momentum exchange between light and nanostructured matter

    Författare :Daniel Andrén; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase-gradient metasurface; optical force and torque; metavehicle; momentum exchange.; nano-optics; rotary nanomotor; optical tweezers;

    Sammanfattning : An object's translational and rotational motion is associated with linear and angular momenta. When multiple objects interact the exchange of momentum dictates the new system's motion. LÄS MER
