Gold nanorods and their plasmonic properties

Abstract

Gold nanorods have been receiving extensive attention owing to their extremely attractive applications in biomedical technologies, plasmon-enhanced spectroscopies, and optical and optoelectronic devices. The growth methods and plasmonic properties of Au nanorods have therefore been intensively studied. In this review, we present a comprehensive overview of the flourishing field of Au nanorods in the past five years. We will focus mainly on the approaches for the growth, shape and size tuning, functionalization, and assembly of Au nanorods, as well as the methods for the preparation of their hybrid structures. The plasmonic properties and the associated applications of Au nanorods will also be discussed in detail.

“Combo” nanomedicine: Co-delivery of multi-modal therapeutics for efficient, targeted, and safe cancer therapy

“…Apoptosis trigged by a chemotherapeutic agent is enhanced when a drug efflux pump (e.g., P-gp) or prosurvival protein (e.g., Bcl-2) is inhibited by RNAi. plasmon resonance (SPR) at the NIR region [209][210][211][212], with high biocompatibility and facile surface functionalization [213,214]. Combined photothermal and chemotherapy via ablation of hepatocellular carcinomas both in vivo and in vitro was explored using gold nanoshells (AuNSs) [215,216] consisting of a mesoporous silica nanorattle core and a thin outer gold shell [215].…”

Highly Sensitive Visual Detection of Copper Ions Based on the Shape-Dependent LSPR Spectroscopy of Gold Nanorods

“…In this work, using cetyltrimethylammonium bromide (CTAB)-stabilized gold nanorods (GNRs), the color of which is dependent on the aspect ratio, 19,20 we have proposed a simple and sensitive visual sensor for Cu 2+ based on the catalytic etching of GNRs. In this system, CTAB acts not only as a stabilizer but also as an ion-association reagent.…”

Quantum coherent plasmon in silver nanowires: A real-time TDDFT study

“…[1][2][3] This collective oscillation leads to an enhanced and confined electric field around the particle. [3][4][5] This phenomenon, called surface plasmon resonance (SPR), has been intensively studied both experimentally [6][7][8][9][10] and theoretically. [11][12][13][14][15][16] Applications include high-sensitivity chemical and biological sensing [17][18][19][20][21][22][23][24][25] as well as energy conversion and storage.…”
