WebHerein, the authors report a seed-mediated strategy for synthesis of chiral-morphology gold nanorods (GNRs) with a novel 222 symmetry as same as that of DNA double helixes. The chiral GNRs with their sides twisted into a double-helical-strip shape are synthesized by the formation of high-Miller-index side surfaces through the regrowth of GNRs. WebChiral objects are widespread in nature, with some examples being DNA and protein. A …
WebApr 4, 2011 · A range of chiral shapes, including tubes with “barber-pole” markings, spiral ribbons (with cylindrical curvature and helical central line), and helicoids (with Gaussian saddle-like curvature and straight central line), have been observed in a rich variety of biological materials and their synthetic analogues. WebMay 14, 2024 · Despite persistent and extensive observations of crystals with chiral shapes, the mechanisms underlying their formation are not well understood. Although past studies suggest that chiral shapes can form because of crystallization in the presence of chiral additives, or because of an intrinsic tenden …
WebMay 14, 2024 · As in Pasteur's experiments, the crystal lattice and shape had the same chiral sense. Unlike the achiral shapes, chirally shaped Te crystallites are structurally imperfect. They are twisted, contain voids, and show structural signatures of one-dimensional lattice defects, namely screw dislocations.

In chemistry, a molecule or ion is called chiral if it cannot be superposed on its mirror image by any combination of rotations, translations, and some conformational changes. This geometric property is called chirality (/kaɪˈrælɪti/). The terms are derived from Ancient Greek χείρ (cheir) 'hand'; which is the canonical example of an object with this property.
