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

Bichiral plasmonic nanoparticles exhibited intriguing geometry-dependent circular dichroism (CD) reversal; however, the crucial factor that dominates CD is still unclear. Combined with spectroscopy and theoretical multipole analysis, we demonstrate originates from excitation of electric quadrupolar plasmons. Moreover, a comparative study two distinct modes reveals correlation between sign local geometric handedness at hotspots, thereby establishing structure-property relationship in bichiral nanoparticles. The reverse attributed to opposite directions wavelength shift plasmon upon changing particle geometry. By finely tuning size nanoparticles, can further reveal dependence on Our work sheds light physical origin provides important guidelines for design chiral toward chirality-dependent applications.

Understanding the crystal facet effect in chiral enantiomer recognition plays an important role designing and fabricating nanozymes for biosensing biodetection applications. Herein, we design ideal platform to study using cubic icosahedral PdPt3 hollow nanocages (NCs) as peroxidase mimics via surface ligand decoration of l/d-cysteine (l/d-Cys). The two NCs have same structure ligand, particle size, wall thickness, area, elemental composition, with only difference exposed facets, i.e., {100} NC-l/d-Cys {111} NC-l/d-Cys. demonstrates 2.2-fold higher peroxidase-like catalytic activity than facet, which also leads better performance discerning 3,4-dihydroxy-l/d-phenylalanine. Our work provides concept tuning high stereoselective properties.
