Chiral metal nanostructures: synthesis, properties and applications

Sulaiman Umar Abbas et al.

Summary: Chirality, the lack of mirror symmetry in objects, is widely observed in nature at different length scales. The physical and chemical properties of chiral complexes have significant applications in fields such as photonics, biochemistry, medicine, and catalysis. The recent flexible design of chiral metal nanostructures provides insights into the origin of chirality and a roadmap for constructing chiral nanomaterials based on specific applications. This review summarizes the various geometries and synthetic approaches to chiral noble metal nanomaterials, discusses their chiroptical properties and potential applications, and proposes opportunities and challenges for their synthesis and application.

Prospects of Surface-Enhanced Raman Spectroscopy for Biomarker Monitoring toward Precision Medicine

Javier Plou et al.

Summary: Future precision medicine relies on the detection of validated biomarkers to classify patients accurately and predict disease risk, prognosis, and treatment response. Surface-enhanced Raman scattering (SERS) spectroscopy, with its high sensitivity and label-free operation, is recognized as a promising technology for clinical monitoring and biomarker discovery. However, there are several variables that need to be considered for accurate SERS monitoring, especially when dealing with biological sources.

Fine-tune chiroptical activity in discrete chiral Au nanorods

Guangchao Zheng et al.

Summary: Accurate research on the applications of chiral plasmonic metal nanoparticles with surface plasmon resonance (SPR) still face challenges. This study demonstrates the production of chiral plasmonic metal nanoparticles with tunable chiroptical activities. The results show that the chiral properties can be precisely tailored by adjusting the longitudinal SPR (LSPR) and the amount of gold nanorods as seeds. The functionalization of a shell of another metal or semiconductor can also achieve a shift of the chiral properties within the UV-vis-NIR region. Chirality transfer from the gold core to the silver shell leads to new chiral properties in the near-UV region.

Helically Grooved Gold Nanoarrows: Controlled Fabrication, Superhelix, and Transcribed Chiroptical Switching

Song Wang et al.

Summary: A new chiral plasmonic nanostructure, helically grooved gold nanoarrows (HeliGNAs), was constructed by introducing L-/D-cysteine during growth, leading to tunable plasmonic circular dichroism. HeliGNAs can self-assemble into a superhelix at high concentrations, establishing a chiroptical switch based on the photoisomerization of an achiral azobenzene derivative. This work deepens the understanding of plasmon-chirality-coupled circular dichroism through exploring interactions between chiral molecules/achiral plasmon and chiral plasmon/achiral molecules.

Bottom-Up Synthesis of Helical Plasmonic Nanorods and Their Application in Generating Circularly Polarized Luminescence

Jiaqi Chen et al.

Summary: This study introduces a chemical strategy for synthesizing intrinsically helical plasmonic nanorods with strong and tailorable plasmonic circular dichroism responses, analyzing the influence of structural parameters on the responses. The depth of the pitch was found to have the greatest impact on the response, and these nanorods were found to induce circularly polarized luminescence of achiral luminophores. The chiral plasmonic nanostructure produced in this study has potential applications in chiral sensors, catalysis, and displays.

Discrete metal nanoparticles with plasmonic chirality

Guangchao Zheng et al.

Summary: Chiral objects lack mirror planes and inversion symmetry, exhibiting the same physical properties as their mirror images except for often opposite chiroptical activity. Recent studies have shown interesting implications of chirality on the optical properties of metal nanoparticles, specifically related to localized surface plasmon resonance phenomena.
