Abstract

The origin of homochirality in life is a fundamental mystery. Symmetry breaking and subsequent amplification of chiral bias are regarded as one of the underlying mechanisms. However, the selection and control of initial chiral bias in a spontaneous mirror symmetry breaking process remains a great challenge. Here we show experimental evidences that laminar chiral microvortices generated within asymmetric microchambers can lead to a hydrodynamic selection of initial chiral bias of supramolecular systems composed of exclusively achiral molecules within milliseconds. The self-assembled nuclei with the chirality sign affected by the shear force of enantiomorphic microvortices are subsequently amplified into almost absolutely chirality-controlled supramolecular gels or nanotubes. In contrast, turbulent vortices in stirring cuvettes fail to select the chirality of supramolecular gels. This study reveals that a laminar chiral microflow can induce enantioselection far from equilibrium, and provides an insight on the origin of natural homochirality.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Vortices, being induced by stirring, microfluidics or temperature gradients, are capable of controlling the handedness of supramolecular helical assemblies.

    “It has been indeed found that vortices, being induced by stirring, microfluidics or temperature gradients, are capable of controlling the handedness of supramolecular helical assemblies.60,[145][146][147][148][149][150][151][152][153][154][155][156][157][158][159]”

    From Possible chemical and physical scenarios towards biological homochirality (2022) · cites this paper as [60]

    The Introduction and Discussion report that microfluidically generated laminar chiral microvortices control the handedness of supramolecular gels and nanotubes. The Introduction also describes stirring-dependent handedness in solution aggregates, but the Results find that turbulent stirring vortices do not control gel chirality. No passage establishes control by vortices induced by temperature gradients. (LLM, conf=0.88)

  • Laminar vortices have been recently employed as the single chiral discriminating source for the emergence of homochiral supramolecular gels in milliseconds.

    From Possible chemical and physical scenarios towards biological homochirality (2022) · cites this paper as [60]

    The Results section (no page number available) says laminar chiral microvortices select the initial chiral bias within tens of milliseconds, and the Discussion reports 96% control over BTAC gel chirality after amplification. The paper supports rapid chiral selection in an achiral-molecule system, but it does not say that fully formed, perfectly homochiral gels emerge within milliseconds. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Hydrothermal vents in primeval oceans are reaction domains often evoked for prebiotic chemistry and may include potential sources of asymmetry such as high-speed microvortices.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
