Scientists from Trinity College Dublin have taken inspiration from nature to create luminescent, self-healing gels with a suite of potential applications ranging from bank note counterfeiting to next-gen bio-sensing and imaging. Crucially, the scientists have been able to introduce guanosine (a ...
“These ground-breaking experiments show that time-resolved circular dichroism is uniquely suited to capture the molecular motion that drives many (bio)chemical processes”
Scientists at EPFL have developed a new laser-based technique that can measure ultrafast changes in the structural symmetry of molecules, called chirality, tracking their conformational shifts in real time. In a collaboration with researchers from the Universities of Geneva and Pisa, the ...
New method can for the first time distinguish their components in liquid form – and more effectively than ever before
Sugars, amino acids, drugs - chiral molecules are everywhere. Researchers in the AQUACHIRAL project at the Fritz-Haber-Institut have used X-rays to study hair-thin liquid jets of these molecules. Using a new method, they can now for the first time distinguish their components in liquid form – and ...
Scientists has found a way to address chiral molecules separately
Using a new experimental method, a team led by physicist Sandra Eibenberger-Arias of the Fritz-Haber-Institut has transferred the mirror-image forms of chiral molecules into different rotational states more efficiently than ever before. This opens doors to a deeper understanding and ...
Chirality: from fundamental particles to biomolecules
If we compare the right to the left hand, we can see these are specular images —that is, like symmetrical shapes reflected in a mirror— and they cannot superimpose on each other. This property is chirality, a feature of the matter that plays with the symmetry of biological structures at different ...
The groundbreaking aspect of her work centers on making circular dichroism ion spectroscopy feasible for large biomolecule ions
Merck, a leading science and technology company, today presented Dr. Valérie Gabelica (44), Inserm, and Director of IECB, Pessac, France, with the 2022 Heinrich Emanuel Merck Award for Analytical Science. The award ceremony took place during the analytical conference EuroFAST2022, Nijmegen, the ...
This discovery is a major breakthrough that will allow researchers to analyse previously unexplored parts of biology and chemistry
Scientists from Durham University’s Chemistry Department have developed the world’s first laser scanning confocal microscope that can harness Circularly Polarised Light (CPL) to differentiate left and right-handed molecules, also known as chiral molecules. The microscope, known as CPL Laser ...
Interference leads to inaccurate Raman spectroscopic analysis of vitamin B12
Many natural products are complicated organic molecules. Despite this complexity, scientists are usually able to investigate them using spectroscopic techniques. However, a team of researchers has now discovered that care should be taken using Raman spectroscopy to analyze certain chiral ...
The spatially resolved determination of which of the two enantiomorphic structural variants - the left-handed or the right-handed - of a chiral phase is present in a polycrystalline material is the focus of a publication in Science Advances. With the EBSD (electron backscatter diffraction) -based ...
New microscope-based spectrometer records both polarization states simultaneously and permitted the first observation of a dynamically moving single nanoparticle
Scientists from the Micro, Nano and Molecular Systems Lab at the Max Planck Institute for Intelligent Systems have developed a new spectroscopic-microscope, which can be used to observe a single nanoparticle in real time. This enabled the first detection of a nanoparticle’s handedness while it is ...
