Deliberate Introduction of Particle Anisotropy in Helical Gold Nanoparticle Superstructures<\/p>\n

Helical nanoparticle (NP) superstructures are an important class of chiral NP assemblies. The nature of the constituent NPs (size and shape) within these assemblies dictates their optical properties. However, the construction of helical NP superstructures consisting of various anisotropic NPs remains challenging. Here, a set of cetyltrimethylammonium bromide derivatives is employed to transform constituent spherical gold NPs (\u22483 nm) within a chiral single\u2010helical assembly into gold nanoprisms (edge length \u2245 10 nm). Careful optimization of this strategy may lead to designed chiral NP architectures with tunable optical properties.<\/p>\n
