Seed‐Mediated Growth and Advanced Characterization of Chiral Gold Nanorods
Source abstract
Abstract
Abstract The controlled growth of gold nanostructures with complex shapes and reduced symmetry, exemplified by chiral gold nanorods and nanoparticles, is one of the most dynamic fields of nanochemistry. A timely summary of underlying concepts, including growth mechanisms and redefined chirality measures, would further promote this research area. In this perspective, we aim to establish qualitative connections between the chiral shapes and growth conditions, specifically for the seed‐mediated synthesis of chiral gold nanorods as a convenient case of chiral morphogenesis. The crystallographic and morphological features of achiral nanorods used as seeds, the experimental conditions during chiral growth, and the symmetry of the chiral inducers, can all be exploited to obtain nanorods with intricate chiral shapes. Chirality characterization (such as electron tomography techniques) and quantification (including chirality measures) emerge as critical aspects to comprehensively explore and understand such structures, enabling optimization of their geometric and optical features. We conclude by discussing relevant challenges to be addressed toward a better controlled synthesis of chiral plasmonic nanostructures.

12. Note: Au nanocrystals also allowed pioneering discoveries in the synthesis of symmetric colloids. In mid‐1850s Faraday discovered stable Au colloidal solutions even though without knowing that the Au colloids were nanosized. The following research on colloidal Au hydrosols also helps Zsigmondy to develop ultramicroscope to study the nature of such colloids. Turkevich etal. developed a robust method to synthesis Au NCs with tunable sizes at 1960s which is now still widely used.
