“Magic mitt”: Morphologically controllable AuAg@AuAg yolk-shell nanostars with better plasmonic optical properties

Cysteine-assisted overgrowth of gold nanorods to prepare highly branched gold nanoantennas with tunable morphological and plasmonic properties

“…[9][10][11][12] The highly tunable LSPR and strong localized fields of anisotropic branch structures make them particularly useful for plasmonics, surface-enhanced Raman scattering (SERS) detection and optical sensing applications. [13][14][15][16][17] Alternatively, AuNPs with branched structures have a relatively large extinction cross section in near-infrared, which is conducive to enhancing photothermal heating capacity, making them ideal candidates for diagnostic and therapeutic medical applications. [18][19][20][21][22] Therefore, it is especially important to accurately control the morphology, such as the branch number, dimensions and aspect ratio during the synthesis.…”

Effect of TiO2 arrays on surface enhanced Raman scattering (SERS) performance for Ag/TiO2 substrates

“…It is well-known that noble metal nanostructures (such as gold and silver) have been extensively used in the preparation of SERS active substrates because of rough morphology and large enhancement factor (EF) [7]. Nevertheless, the noble metal materials suffer from some defects such as low reproducibility, high price, weak stability and poor biocompatibility.…”
