Imprinting chirality in inorganic nanomaterials for optoelectronic and bio-applications: strategies, challenges, and opportunities

Abstract

We have shed light on the recent advances in imprinting chirality into achiral inorganic nanomaterials using organic chiral molecules, their structural analysis, growth mechanism, optical, optoelectronic, and bio-applications.

Design of functional nanoparticles by microfluidic platforms as advanced drug delivery systems for cancer therapy

“…Inorganic-based NPs are widely used in a variety of fields, such as optoelectronics, 130 imaging, 131 sensing, 132 catalysis 133 and especially in the drug delivery field, 134 due to their unique physicochemical properties on the nanoscale. Thanks to the advantages mentioned above, microfluidic technologies have been widely employed for the fabrication and surface modification of inorganic nanomaterials, such as metal and metal/metal composite NPs, 135 silica NPs, 136 metal–organic frameworks (MOFs) 137 and quantum dots (QDs).…”

A supramolecular assembly-based strategy towards the generation and amplification of photon up-conversion and circularly polarized luminescence

“…Chiral objects are found ubiquitously in nature and in many cases are endowed with characteristic chiroptical properties. 91 There are several chiroptical methods that are used to characterize the stereochemical and electronic properties of chiral molecules. Standard measurements performed to investigate chiroptical properties are circular dichroism (CD) and optical rotatory dispersion.…”

Classical nexus between chiral inducers and achiral silver nanoparticles and integration of the digital XOR logic gate

“…[22][23][24][25] The enhancement of chiroptical property in chiral ligand-linked nanomaterials due to the electronic transitions (interband and intraband) is related to the nonzero dot product of electric and magnetic dipole transition moments. 10,26,27 To control the surface morphology, size, reactivity, and shape of nanoparticles by introducing inherent chirality is a challenging task; however, efforts have been made to overcome these obstacles. [28][29][30][31] Chirality induction into achiral metallic nanomaterials has received increasing attention because the method offers the ability to achieve strong optical activity over a broad spectral range.…”
