Chiroptoelectronic devices are crucial for applications in quantum computing, spin optical communications, and magnetic recording. However, the limited efficiency and low stability of conventional circularly polarized light (CPL)-sensing materials have restricted their broader use. Here, we introduce atomic chiral Se nanorod (NRs) films as broadband CPL detectors, leveraging the intrinsic chirality and stability of Se nanocrystals. We also perform incident circular polarization (ICP)-Raman optical activity (ROA) to explore the chiroptical activity of the large-area films. The Se NRs thin films detected CPL across a broad range from ultraviolet (UV) to short-wavelength infrared (SWIR), with a responsivity dissymmetry factor of up to 0.4, maintaining high stability under ambient conditions for longer than 13 months. CPL-sensitive Se NRs with intrinsic chirality have potential applications in chiral photonic synapses, chiral spin devices, and CPL-sensitive photocatalysts. ICP-ROA mapping also advances the analysis of 2D chiral materials.

Chirality transfer has garnered significant attention due to its potential to revolutionize asymmetric synthesis of enantiopure compounds and to provide fundamental insights into molecular symmetry breaking, which is widely believed to underlie the pervasive phenomenon of homochirality in biological systems. While organic-to-organic and organic-to-inorganic chirality transfers have been extensively studied, the inorganic-to-organic counterpart remains challenging due to the dimensional mismatch between the nanoscale of inorganic materials and the molecular scale of organic compounds, the thermodynamic instability of chiral inorganic lattices, and the uncontrollable influence of defects on chirality transfer. This review summarizes the synthesis of organic-free chiral nano-inorganic materials and explores the concept of inorganic-to-organic chirality transfer via symmetry breaking induced by these materials through three proposed pathways: enantiospecific inorganic-organic interactions, chirality transfer from circularly polarized light to molecules, electron spin-determined enantiopreferential reactions governed by chiral-induced spin selectivity.

The prebiotic synthesis and symmetry breaking of ribose are crucial processes in the origin of life. However, the prebiotic emergence of enantiomerically enriched ribose on primitive Earth remains an unresolved challenge. Herein, we propose that the prebiotic enantioselective synthesis of ribose from glycolaldehyde and glyceraldehyde can be catalyzed by minerals naturally endowed with chiral structure.

The early diagnosis of neurodegenerative diseases, such as Alzheimer's disease (AD), requires the identification of sensitive and specific biomarkers. Detecting chiral molecules at concentrations relevant to disease states remains challenging. Herein, a new type of chiral gold nanostructure induced by D-/L-cysteine-leucine dipeptides with a g-factor of 0.
