Synthesis and Morphology of Star-Shaped Gold Nanoplates Protected by Poly(N-vinyl-2-pyrrolidone)

Spatially resolved measurements of plasmonic eigenstates in complex-shaped, asymmetric nanoparticles: gold nanostars

“…Their particular shape, plus the fact that they are made of gold (very stable and biocompatible), makes them suitable for several applications, including biosensing on live cells [9] or Surface Enhanced Raman Spectroscopy (SERS) detection of very low concentrations of molecules [10]. Nanostars with different symmetry levels, aspect ratios and number of tips have been synthesized by several research groups [9,[11][12][13][14]. Their optical properties have been explored by means of many different experimental and numerical techniques such as UV-visible scattering [11,14], Rayleigh scattering in a dark-field microscope [9,15], SERS [10,13], Finite Difference Time Domain (FDTD) simulations [16], Boundary Elements Method (BEM) [10,14] and Discrete Dipole Approximation (DDA) calculations [9,11].…”

Synthesis of Trisoctahedral Gold Nanocrystals with Exposed High‐Index Facets by a Facile Chemical Method

“…[1a, [4][5][6][7][8][11][12][13] Very recently, Sun and co-workers prepared tetrahexahedral platinum NCs enclosed by 24 high-index facets (such as {730}, {210}, and {520}) by an electrochemical method for the first time, and found that these high-index surfaces are thermally and chemically stable and exhibit enhanced catalytic activity. [15] The interesting shape and properties of such tetrahexahedral platinum NCs have inspired great efforts to synthesize wellshaped metal NCs with high-index facets by means of some facile methods.…”

Biomedical Applications of Plasmon Resonant Metal Nanoparticles

“…Silver nanoparticles can be synthesized with controlled shape and optical properties guided by optical illumination [18]. More complex architectures have also been described, including gold nanocages [19][20][21], elongated core-shell geometries [22] and gold nanostars [23][24][25][26][27][28].…”
