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 ...

Dumbbell-Like Silica Coated Gold Nanorods and their Plasmonic Properties.
Langmuir, 2019Silica coated gold nanorods with dumbbell-like morphology allowing dual functionalization in an individual nanostructure have attracted great attention for applications such as sensing and biological imaging. We report a detailed study on the feasibility

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: Plasmonic Photoheating
2015Nanomaterials offer unique properties that bridge classic to quantum behavior of matter. Gold nanoparticles (GNPs) are a relevant class of nanomaterials that has gained considerable attention for potential applications in medicine due to their size-dependent electronic, optical, and chemical properties.

pH-Triggered Assembly of Gold Nanorods
Langmuir, 2005The self-assembly of surfactant-protected gold nanorods (aspect ratio 3.3 +/- 0.3, 20.6 +/- 5.5 nm width, and 67.5 +/- 9.0 nm length) into ordered structures using adipic acid is presented. As made, the gold nanorods are coated with cationic surfactant, which gives them a net positive charge in aqueous solution. The pH-dependent assembly is directed by

Electrochemical Charging of Single Gold Nanorods
Journal of the American Chemical Society, 2009Metal nanocrystals are commonly used to mediate important chemical reactions such as water splitting and CO oxidation. To investigate such redox reactions in detail, it would be useful to be able to carry out electrochemistry on single metal nanocrystals.

Spectroscopic Photoacoustic Imaging of Gold Nanorods
2017Photoacoustic imaging is a rapidly developing tool capable of achieving high-resolution images with optical contrast at imaging depths up to a few centimeters. When combined with targeted nanoparticle contrast agents, sensitive detection of molecular signatures is possible.
