“…Correspondingly, easy cellular uptake of exogenetic materials can also cause higher biological effects. For example, Cui's group reported that D-GSH coated Au NCs can generate more ROS and exhibit higher PDT efficiency that L-GSH coated Au NCs in the treatment gastric carcinoma 99 , 187 . Similarly, Xu's group also reported that D-Cys-MoO 2 and D-Cys-MoO 2.83 demonstrated higher PTT efficiency than the L-ones 6 .…”

The rapid development of chiral inorganic nanostructures has greatly expanded from intrinsically chiral nanoparticles to more sophisticated assemblies made by organics, metals, semiconductors, and their hybrids. Among them, lots of studies concerning on hybrid complex of chiral molecules with achiral nanoparticles (NPs) and superstructures with chiral configurations were accordingly conducted due to the great advances such as highly enhanced biocompatibility with low cytotoxicity and enhanced penetration and retention capability, programmable surface functionality with engineerable building blocks, and more importantly tunable chirality in a controlled manner, leading to revolutionary designs of new biomaterials for synergistic cancer therapy, control of enantiomeric enzymatic reactions, integration of metabolism and pathology via bio-to nano or structural chirality. Herein, in this review our objective is to emphasize current research state and clinical applications of chiral nanomaterials in biological systems with special attentions to chiral metal- or semiconductor-based nanostructures in terms of the basic synthesis, related circular dichroism effects at optical frequencies, mechanisms of induced optical chirality and their performances in biomedical applications such as phototherapy, bio-imaging, neurodegenerative diseases, gene editing, cellular activity and sensing of biomarkers so as to provide insights into this fascinating field for peer researchers.

“…Chiral form Asymmetric sp 3 promising in new technological solutions in many fields, such as biosensing, chiral catalysis, chiral resolution, biomedical imaging, information technologies like quantum computing, and so forth. 1 Coupling chiroptical properties with other physical properties would be easy due to the virtue of inorganics, which could offer new perspectives on material science as well. Moreover, a deeper understanding of the inorganic chirality can not only shed light on possible answers to the homochirality on Earth but also help to design complicated biomimetic chiral technologies.…”

“…The D-cysteine would bind~0.3 kcal/mol stronger than L-cysteine on an S-type Au (17,11,9) surface ( Figure 6B), 100 and such asymmetric adsorption has been confirmed by X-ray photoelectron spectroscopy. 96 Gellman et al 101 used temperature-programmed desorption (TPD) to measure the R-3-methylcyclohexanone desorption on different chiral Cu surfaces, such as (643), (653), (651), (13,9,1), (17,5,1), (821), and (531). The |ΔΔE des | was found to range from~0.63 to 1.08 kcal/mol.…”

“…Chiral molecules are found important in life science, agrochemicals, pharmaceutical industries, biosensing, display materials, and so forth. [1][2][3][4][5] Chirality stems from a structure lacking symmetry elements of inversion symmetry and mirror-plane, which makes the structure not superimposable with its mirror image. Without these two kinds of symmetries, any structure is chiral, besides conventional chiral organics or spiral inorganic structures.…”

Chiral molecules are found important in life science, agrochemicals, pharmaceutical industries, biosensing, display materials, and so forth 1–5 . Chirality stems from a structure lacking symmetry elements of inversion symmetry and mirror‐plane, which makes the structure not superimposable with its mirror image.…”

Chirality communications between inorganic and organic compounds bridge the gap between different materials. The transfer is mainly realized by material hybridization andasymmetric synthesis, while the recognition is usually carried out in the form of enantioselective adsorption of organics on inorganics. The transfer and recognition can enlarge the number of chiral materials, which may lead to new applications in many fields.

Fabricating chiral inorganic materials and revealing their unique quantum confinement‐determined optical chiral responses are crucial tasks in the multidisciplinary fields of chemistry, physics, and biology. The field of chiral mesostructured inorganic materials started from the synthesis of individual nanocrystals and evolved to include their assembly from metals, semiconductors, ceramics, and inorganic salts endowed with various chiral structures ranging from atomic to micron scales. This tutorial review highlights the recent research on chiral mesostructured inorganic materials, especially the novel expression of mesostructured chirality and endowed optical chiral response, and it may inspire us with new strategies for the design of chiral inorganic materials and new opportunities beyond the traditional applications of chirality. Fabrication methods for chiral mesostructured inorganic materials are classified according to chirality type, scale, and symmetry‐breaking mechanism. Special attention is given to highlight systems with original discoveries, exceptional phenomena, or unique mechanisms of optical chiral response for left‐ and right‐handedness.
