Multiplex Biosensor Using Gold Nanorods
Analytical Chemistry, 2006Gold nanorods (GNRs) with different aspect ratios were fabricated through seed-mediated growth and surface activation by alkanethiols for the attachment of antibodies to yield gold nanorod molecular probes (GNrMPs). Multiplex sensing was demonstrated by the distinct response of the plasmon spectra of the GNrMPs to binding events of three targets (goat ...

Surfactant (Bi)Layers on Gold Nanorods
Langmuir, 2011Gold nanorods in aqueous solution are generally surrounded by surfactants or capping agents. This is crucial for anisotropic growth during synthesis and for their final stability in solution. When CTAB is used, a bilayer has been evidenced from analytical methods even though no direct morphological characterization of the precise thickness and ...

Seed mediated growth of gold nanorods: towards nanorod matryoshkas
Faraday Discussions, 2016After a brief review of anisotropy on the nanoscale, experiments in which nanorod core–shell–shell particles are grown are presented. These “nanomatryoshkas” consist of a gold nanorod core, a silica shell, and a final gold shell. Calculation of the near-field properties of these structures using the discrete dipole approximation uncovers the change in ...

Biofunctionalization of gold nanorods
Pure and Applied Chemistry, 2010Gold nanorods (NRs) are promising nanomaterials for biotechnology innovations that include photoassisted drug delivery, gene therapy, noninvasive cancer detection, and ultrasensitive biodetection. Owing to their unique geometry, Au NRs exhibit surface plasmon (SP) modes in the near-infrared (IR) wavelength range—ideal for carrying out optical ...

Gold nanorod extinction spectra
Journal of Applied Physics, 2006Geometrical factors suitable for use in Mie–Gans theory are derived from discrete dipole aproximation generated spectra for a number of pseudonanorods permitting the rapid calculation of extinction spectra. It is shown that the rod width, rod end-cap geometry (flat, oblate spheroid, and sphere) and the rod size distribution all have a significant ...

Gold nanorods: Synthesis, characterization and applications
Coordination Chemistry Reviews, 2005Abstract This article provides an overview of current research into the synthesis and properties of gold nanorods. Interest in rod-shaped nanoparticles stems from their unique optical properties, which can be approximated by Mie–Gans theory. We begin by outlining briefly the origin of the shape-dependent optical properties of rods.
