Journal ArticleDOI
Shape-controlled synthesis of metal nanostructures: the case of silver.
TL;DR: Investigating the growth mechanisms for silver nanocubes, nanowires, and nanospheres produced through a polymer-mediated polyol process found that the crystallinity of a seed and the extent of the PVP coverage on the seed were both instrumental in controlling the morphology of final product.
Journal ArticleDOI
Localized surface plasmon resonance spectroscopy of single silver nanocubes
Leif J. Sherry,Shih-Hui Chang,George C. Schatz,Richard P. Van Duyne,Benjamin J. Wiley,Younan Xia +5 more
TL;DR: In this work, dark-field microscopy is used to observe a new plasmon resonance effect for a single silver nanocube in which the plAsmon line shape has two distinct peaks when the particles are located on a glass substrate.
Journal ArticleDOI
Synthesis of silver nanostructures with controlled shapes and properties.
TL;DR: This work selectively produced pentagonal nanowires, cuboctahedra, nanocubes, nanobars, bipyramids, and nanobeams of silver with a solution-phase polyol synthesis by controlling the crystallinity of the seeds from which nanostructures grow and the rate of atomic addition to seeds.
Journal ArticleDOI
Maneuvering the Surface Plasmon Resonance of Silver Nanostructures through Shape-Controlled Synthesis
Benjamin J. Wiley,Sang Hyuk Im,Zhi-Yuan Li,Joeseph McLellan,and Andrew R. Siekkinen,Younan Xia +5 more
TL;DR: With a series of discrete dipole approximation (DDA) calculations, each of a distinctive morphology, it is illustrated how shape control can tune the optical properties of silver nanostructures.
Journal ArticleDOI
Gold nanocages: bioconjugation and their potential use as optical imaging contrast agents.
Jingyi Chen,Fusayo Saeki,Benjamin J. Wiley,Hu Cang,Michael J. Cobb,Zhi-Yuan Li,Leslie Au,Hui Zhang,Michael B. Kimmey,Xingde Li,Younan Xia +10 more
TL;DR: By controlling the molar ratio between Ag and HAuCl4, the gold nanocages could be tuned to display surface plasmon resonance peaks around 800 nm, a wavelength commonly used in optical coherence tomography (OCT) imaging.
