Metallic gyroids with broadband circular dichroism

, 2018
Circular dichroism is a useful property for filtering or separating beams containing opposite spin angular momentum. Of the many geometries exhibiting circular dichroism, the gyroid has proven to be an excellent template for exploring circular dichroism ...

Chiroptical and Magneto‐Optical Properties of Chiral Copper Phthalocyanine‐Based Thin Films

ChemistryEurope
Chirality, once considered unrelated to magnetism, has recently been recognized to couple with magnetic fields through magneto‐chiral anisotropies (MChAs), such as magneto‐chiral dichroism (MChD).

Investigation on the Recognition of Split Aflatoxin M1 Aptamer

Shipin gongye ke-ji
In this work, AFM1 was chosen as the target, and the aptamer was split to solve the low sensitivity due to unstable structure of the aptamer. The recognition ability and specificity of the split aptamer were evaluated using electrochemical methods, and ...

Giant Circular Dichroism in Individual Carbon Nanotubes Induced by Extrinsic Chirality

Physical Review X, 2014
Circular dichroism is widely used for characterizing organic and biological materials, but measurements at a single-molecule level are challenging because differences in absorption for opposite helicities are small. Here, we show that extrinsic chirality

Indole alkaloid sulfonic acids from an aqueous extract of Isatis indigotica roots and their antiviral activity

Acta Pharmaceutica Sinica B, 2017
Six new indole alkaloid sulfonic acids (1–6), together with two analogues (7 and 8) that were previously reported as synthetic products, were isolated from an aqueous extract of the Isatis indigotica root.

A Computational Strategy for Identifying Self‐Assembling Food‐Derived Molecules for Antiparasitic Nanotherapy

Advanced Science, EarlyView.
An integrated computational screening strategy identified ursolic acid (UA) and 18β‐glycyrrhetinic acid (18βGA) as a self‐assembling food‐derived molecular pair. The resulting carrier‐free nanoparticles (UA‐18βGA) showed synergistic antiparasitic activity, reduced combined toxicity, and host‐protective anti‐inflammatory effects in zebrafish and murine ...

Engineering Microbial Particles for Next‐Generation Biomedical Platforms

Advanced Science, EarlyView.
Microbe‐derived particles (MDPs), which include extracellular vesicles, outer membrane vesicles, inclusion bodies, polysaccharide particles, and virus‐like particles, represent a rapidly expanding category of bioinspired nanomaterials. With their natural origin, intrinsic biocompatibility, and highly programmable functionality, MDPs serve as a ...

Analysis of Circular Dichroism and Linear Dichroism Spectroscopy

, 2012
Circular Dichroism (CD) and Linear Dichroism (LD) spectroscopies measure the difference in absorption between left and right circularly polarized light and parallel and perpendicular linearly polarized light as a function of wavelength respectively.

Helicalization of Covalent Organic Framework Nanofibers with Amplified Spin Polarizability for Boosting Photocatalytic Hydrogen Evolution

Advanced Science, EarlyView.
A non‐covalent chirality‐induced strategy via chiral solvents is presented to synthesize helical 2D COF nanofibers with high crystallinity, high chirality, and high spin polarization. The helical structure enhances the concentration of photogenerated charges, suppresses exciton recombination, and extends carrier lifetimes, thereby significantly ...
