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

    Author : Daniel Andrén; Chalmers tekniska högskola; []
    Keywords : 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;

    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.

  4. 2. Colloidal interactions obtained from total internal reflection microscopy measurements and scattering data

    Author : Moheb Nayeri; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; total internal reflection microscopy; colloidal stability; van der Waals interaction; Debye length; surfactants; depletion; scattering; colloidal stability;

    Abstract : The scattering of radiation can be used to extract information about the interactions between colloidal (10^{-7}-10^{-3} cm radius) particles suspended in liquids. As colloidal interactions incorporate entropic effects they are weak and while system specific they are governed by a number of general mechanisms. READ MORE
