Synthesis and SERS Properties of Nanocrystalline Gold Octahedra Generated from Thermal Decomposition of HAuCl₄ in Block Copolymers

Block Copolymer Nanolithography: Translation of Molecular Level Control to Nanoscale Patterns

“…[188][189][190] In a similar fashion encapsulated quantum dots have been prepared [191] and PS-b-PEO diblock micelles used to produce various metal clusters. [192,193] Although major interest for the metal solution process coding are focused on bulk or micelles of BCPs, [194][195][196][197][198][199] a number of studies demonstrate the significant potential of this process. Sohn and Seo [200] first employed such in situ coding of metal nanoparticles in PS-b-P4VP thin films, as displayed in Figure 15.…”

Wafer-Scale Leaning Silver Nanopillars for Molecular Detection at Ultra-Low Concentrations

“…A broad variety of SERS substrates have been fabricated over the past decade, e.g. nanorods 8 , nanocubes 9 , nanostars 10 , various particle arrays [11][12][13][14][15][16] and silver dendrites 17 . Recently electric field (E-field) enhancement factors (EF) above 10 8 to even 10 10 have been reported.…”

Uniform Fe3O4 Octahedra with Tunable Edge Length – Synthesis by a Facile Polyol Route and Magnetic Properties

“…[10][11][12][13][14][15][16][17] Polyhedral particles, as a special type of faceted materials, have been demonstrated to possess unique properties associated with their facets, edges, and even corners. [18][19][20][21] Alkali metals can move easily on the Fe 3 O 4 (111) surface, consequently the catalytic ability of the defined alkali metal can be enhanced. [22] Despite some progress in the synthesis of micro/ sub-microscale and nanoscale Fe 3 O 4 octahedra, [23,24] the synthesis of Fe 3 O 4 octahedra having tunable size, sharp edge length distribution, and uniform shape have met with very limited success.…”
