Anisotropy Analysis of Bamboo and Tooth Using 4‐Angle Polarization Micro‐Spectroscopy

open access: yesNano Select, EarlyView.
Super‐resolution via orientation: spatial distribution of specific molecular vibrations are revealed at 1/20 of the diffraction limit. ABSTRACT To investigate the anisotropic properties of biomaterials, two distinct classes are considered as follows: polymer‐based (cellulose in plants) and crystalline‐based (enamel in teeth), each demonstrating ...

Computational Study on Potentially Active Antibacterial Compounds in Secondary Metabolites of Extremophilic Microorganisms

open access: yesChemistryOpen, EarlyView.
This study employed density functional theory (DFT) and conceptual DFT (CDFT) to calculate the structures and properties of potential antibacterial compounds derived from 16‐membered lactone ring‐containing secondary metabolites of extremophiles, as well as midecamycin.

Biological and structural properties’ interpretation on antitumour drug 3-(2-aminoethyl) indole (tryptamine) using molecular spectroscopy and computational tools

open access: yesJournal of Taibah University for Science, 2019
In this work, the known and unknown structural as well as biological properties of 3-(2-aminoethyl) indole (tryptamine) were interpreted using molecular spectroscopy (FT-IR, FT-Raman, NMR and UV–Visible) and cheminformatic tools.

Large‐Area Metallic Nanohelices for Engineering Optical Chirality

open access: yesSmall, EarlyView.
By exploiting the nanoscale engineering of residual stresses in metallic thin films, this method enables scalable fabrication of submicrometer metallic helices with tunable geometry and material versatility. The resulting structures exhibit pronounced chiroptical responses across the mid‐ to near‐infrared range, offering a robust platform for chiral ...

A Comparative Study on Interactions of Antimicrobial Peptides L- and D-phenylseptin with 1,2-dimyristoyl-sn-glycero-3-phosphocholine

open access: yesApplied Sciences, 2019
L-phenylseptin (L-Phes) and D-phenylseptin (D-Phes) are amphibian antimicrobial peptides isolated from the skin secretion of Hypsiboas punctatus. In the N-termini, L-Phes and D-Phes contain three consecutive phenylalanine residues, l-Phe-l-Phe-l-Phe and ...

Intrinsically Chiral Excimers: Water‐Compatible Trityl‐Based Nanoparticles as Tailored Dual Emitters of Circularly Polarized Luminescence in the Vis or NIR Regions

open access: yesSmall, EarlyView.
Dual circularly polarized luminescence (CPL) is demonstrated in pioneering metal‐free organic nanoparticles (ONPs) from a brominated trityl radical derivative. CPL activity in the Vis or NIR regions in aqueous environments is achieved by tayloring the content of radical enantiomers in ONPs, thanks to the generation of intrinsically chiral excimers ...

A Stern-Gerlach separator of chiral enantiomers based on the Casimir-Polder potential

open access: yes, 2018
We propose a method to separate enantiomers using parity violation in the Casimir-Polder potential between chiral mirrors and chiral molecules. The proposed setup involves a molecular beam composed of chiral molecules passing through a planar cavity ...

Preparation of Aqueous Solutions with Information on Solids Using Natural Polymers by Solid‐State Mixing

open access: yesThe Chemical Record, EarlyView.
The solid‐state information, such as chiral crystal formation, crystal polymorphism, mechanochromism, room‐temperature phosphorescence, and fluorescence detection by molecular recognition, is maintained even when the functional guest molecules are solubilized in water using natural polymers.

Fluorescent proteins: A journey from the cell to extreme environments in material science

open access: yesPhotochemistry and Photobiology, EarlyView.
Applications of proteins and microorganisms as tools or effectors in material science. Abstract This review presents the progression from the use of fluorescent proteins (FPs) and chromoproteins as bioimaging labels and sensors to the strategic engineering of their properties for robust functionality in synthetic and non‐biological environments ...
