Chiral nanomaterials are emerging as a promising class of vaccine adjuvants with the potential to significantly enhance vaccine efficacy, especially in the context of cancer immunotherapy.

This work discusses the imprinting of optoelectronic chirality on hybrid-organic inorganic perovskites, which are a new class of chiral nanomaterials for manipulation and control of spin polarized current and circularly polarized light.

We summarize the latest developments in NIR-CPL generated by chiral inorganic nanomaterials and provide new perspectives for constructing NIR-CPL materials and developing new applications for chiral nanomaterials.

Review of synthesis strategies for circularly polarized luminescence (CPL) inorganic quantum dots, influencing factors, theoretical insight into CPL mechanisms, and future applications/prospects. Images reproduced with permission, details in article.

This review covers fundamental principles and techniques for measuring chiral properties as well as the synthesis of chiral sulfur-based nanomaterials, their optical and chiroptical properties, and possible applications.

Here, we report on the magneto-chiral dichroism of a chiral nanomagnet showing magneto-electric coupling. These results represent the first evidence of the coexistence of magneto-chiral dichroism and magneto-electric coupling at room temperature.

Homochiral selective secondary nucleation, promoted by the choice of solvent or stirring, was suggested as the key process for the emergence of macroscopic chiral symmetry breaking in the gelation of Fmoc amino acids.

Multicolor CPL materials with controllable handedness were constructed from nonchiral luminescent charge transfer complexes through co-assembly with chiral N-terminal aromatic amino acids.

In the system for the in situ synthesis of side-chain cyanobiphenyl block copolymer assemblies, varying the spacer units in CB monomers revealed two distinct odd–even effects.

Optically active persistent luminescent materials are highly promising for anticounterfeiting applications due to their distinct luminescent features and the ability to display unique optical polarization properties.

The active layer of solar cells in gradient films of a small molecule acceptor and a chiral donor were imaged using Mueller matrix polarimetry showing thickness dependence in supramolecular organization reflected in optoelectronic behaviour.

Gold nanoparticles capped with photoactive azo ligands exhibit tunable optical properties through SPR modulation. The ligands, synthesized without reducing agents, induce a chiral lamellar superstructure in the nanoparticles.

A moiré metasurface, consisting of two sheets of suspended bilayer metagratings, is demonstrated with active near-infrared-I chiroptical responses in both its sign and magnitude, which is exploited for label-free chirality detection.

Two pairs of enantiomers were obtained via self-assembly of sulfonylcalix[4]arene tetranuclear M(II) clusters (M = Co or Ni) with enantiomerically enriched linkers based on tris(dipyrrinato)cobalt(III) complexes, leading to nanosized porous cages.

Single chiral ligand coordination effectively deracemizes intrinsically chiral Au₁₃ clusters with binary mixed ligands of chiral and achiral diphosphines.

This study reports the synthesis and characterisation of a ferrocene-based conjugated polymer and a chiral composite.

Enantiopure and racemic neutral Ni(II) and Pt(II) bis(dithiolene) complexes, based on the de-dddt ligand and prepared by electrocrystallization of the anionic precursors, crystallize in enantiomorphic space groups and are band gap semiconductors.

This study develops a highly sensitive chiroptical sensor for detecting Hg²⁺ and I⁻ ions through the co-assembly of G-quartet nanofibers and N–S-CDs.

Symmetry breaking in chiral porphyrin aggregates magnifies chiral impurities in clay.

Nanostructured oligodimethylsiloxane-helicene-pyrene chiral materials exhibit an excimeric response and improved CPL activity in the bulk state.

Chiral nematic mesoporous organosilica (CNMO) films have unique iridescent properties that make them attractive candidates for decorations, sensing and photonics.

Nanoscale chirality exists in inorganic zinc(II) orthophosphates as confirmed by solid state vibrational circular dichroism.

Nanorod-based plasmonic circular dichroism distinguishes the composition and features of different αSyn fibrils.

The supramolecular polymerization of the [6]helicene-based luminophores 1 and 2, showing a rich dichroic pattern, is reported. The inherent chirality of both the monomeric and aggregated species of 1 and 2 provides the systems with a remarkable overall CPL-efficiency.

Real-time circularly polarised imaging is achieved using two low-cost (<£2000) and compact imaging systems controlled by open-source python software.
