Shape‐Controlled Synthesis of Metal Nanocrystals: Simple Chemistry Meets Complex Physics?
TL;DR: A comprehensive review of current research activities that center on the shape-controlled synthesis of metal nanocrystals, including a brief introduction to nucleation and growth within the context of metal Nanocrystal synthesis, followed by a discussion of the possible shapes that aMetal nanocrystal might take under different conditions.

Silver as Antibacterial Agent: Ion, Nanoparticle, and Metal
TL;DR: It can be concluded that the therapeutic window for silver is narrower than often assumed, however, the risks for humans and the environment are probably limited.

Electromagnetic fields around silver nanoparticles and dimers.
Encai Hao,George C. Schatz +1 more
TL;DR: The discrete dipole approximation is used to investigate the electromagnetic fields induced by optical excitation of localized surface plasmon resonances of silver nanoparticles, including monomers and dimers, with emphasis on what size, shape, and arrangement leads to the largest local electric field (E-field) enhancement near the particle surfaces.
Journal ArticleDOI
Controlling anisotropic nanoparticle growth through plasmon excitation
TL;DR: It is demonstrated that the previously described photoinduced method for converting silver nanospheres into triangular silver nanocrystals—so-called nanoprisms—can be extended to synthesize relatively monodisperse nanoprism with desired edge lengths in the 30–120 nm range.

Nanoscale Forces and Their Uses in Self‐Assembly
TL;DR: This Review provides a critical examination of the various interparticle forces (van der Waals, electrostatic, magnetic, molecular, and entropic) that can be used in nanoscale self-assembly.

Probing Single Molecules and Single Nanoparticles by Surface-Enhanced Raman Scattering
Shuming Nie,Steven R. Emory +1 more
TL;DR: In this article, surface-enhanced Raman scattering was used to detect single molecules and single nanoparticles at room temperature with the use of surface enhanced Raman, and the intrinsic Raman enhancement factors were on the order of 10 14 to 10 15, much larger than the ensemble-averaged values derived from conventional measurements.

A study of the nucleation and growth processes in the synthesis of colloidal gold
TL;DR: In this paper, a preliminary survey with the electron microscope of various preparations of colloidal gold, a study was made of the process of nucleation and growth in gold colloids, and it was shown that nucleating agents may be identified with reducing agents which form a mixed polymer with chlorauric ion before the reduction to the nucleus takes place.

Photoinduced conversion of silver nanospheres to nanoprisms.
TL;DR: This light-driven process results in a colloid with distinctive optical properties that directly relate to the nanoprism shape of the particles, which could be useful in developing multicolor diagnostic labels on the basis of nanoparticle composition and size but also of shape.

DNA-templated assembly and electrode attachment of a conducting silver wire
TL;DR: A two-step procedure that may allow the application of DNA to the construction of functional circuits and confirms that the recognition capabilities of DNA can be exploited for the targeted attachment of functional wires.

Shape effects in plasmon resonance of individual colloidal silver nanoparticles
TL;DR: In this paper, the effect of size and shape on the spectral response of individual silver nanoparticles was studied and it was shown that specific geometrical shapes give distinct spectral responses.
