  • Method of making nanoparticles by electroless plating
    Patent number: 8097295
    Abstract: A plurality of gold nanoparticles disposed on a surface of a substrate includes nanoparticles having an average particle density greater than 1.8×1011 particles per squared centimeter of the surface. The gold nanoparticles include a monomodal diameter distribution and an average diameter capable of being arbitrarily controlled between about 5 nm to about 300 nm. The surface may be a three-dimensional surface or an internal surface.
    Type: Grant
    Filed: February 27, 2008
    Date of Patent: January 17, 2012
    Assignee: The University of Utah Research Foundation
    Inventors: Donald Keith Roper, Wonmi Ahn, Benjamin Jeppson Taylor, Analía G. Dall'Asén
  • INCREASING HEAD TRANSDUCTION VIA SURFACE PLASMON RESONANCE BY MODULATING RESONANT CONTINUOUS-WAVE IRRADIATION
    Publication number: 20100163533
    Abstract: The present invention relates to methods and apparatus for increasing the conversion efficiency of irradiation incident on metal particles to an ambient environment. More specifically the invention relates to methods and apparatus for increasing the heat conversion efficiency from irradiation incident on metal particles to an ambient environment through modulating radiation incident upon the metal particles.
