PFAS analysis: Reliably detecting eternity chemicals

analytica conference: PFAS in the focus of science

27-Feb-2024 - Perfluorinated and polyfluorinated alkyl substances (PFAS) are colloquially known as “eternity chemicals” due to their persistence in the environment. PFAS do not occur naturally, but they can be found in all sorts of things from food packaging and outdoor textiles to seals and hoses. This group ...

A miniature magnetic resonance imager made of diamond

Quantum sensors make microscale NMR spectroscopy possible

23-Oct-2023 - The development of tumors begins with miniscule changes within the body's cells; ion diffusion at the smallest scales is decisive in the performance of batteries. Until now the resolution of conventional imaging methods has not been high enough to represent these processes in detail. A research ...

Benchtop NMR spectroscopy can accurately analyse pyrolysis oils

More accessible analysis could help develop the potential of bio-oils as an alternative to fossil fuels

12-Sep-2023 - A team of researchers at Aston University has demonstrated that benchtop spectrometers are capable of analysing pyrolysis bio-oils just as well as far more expensive, high-field spectrometers. Bio-oils resulting from the intense heating (pyrolysis) of industrial or agricultural by-products, are ...

Inflammation Values by Spectrometry

Quantifying acute-phase inflammation proteins by NMR

27-Jul-2023 - The analysis of all small molecules in an organism (the metabolome) has huge potential for medical diagnostics. A German research team is investigating this with nuclear magnetic resonance spectrometry (NMR). In a study recently published in Angewandte Chemie, they quantified acute-phase proteins ...

Less risk, less costs: Portable spectroscopy devices could soon become real

New approach to enable measurements without strong magnetic fields

06-Sep-2022 - Nuclear magnetic resonance (NMR) is an analytical tool with a wide range of applications, including the magnetic resonance imaging that is used for diagnostic purposes in medicine. However, NMR often requires powerful magnetic fields to be generated, which limits the scope of its use. Researchers ...

Exposing what’s in tattoo ink

Ingredient lists often aren’t accurate

29-Aug-2022 - From life-like faces to elaborate nature scenes, tattoos are a true art form. Although people have decorated their bodies for millennia for ceremonial and religious reasons, many people today adorn themselves with these images as a form of self-expression. But the inks used for tattoos are ...

Pimp my Spec: Upgrade for Magnetic Resonance Methods with a 1,000-fold Amplifier

Atomistically accurate description of proteins at native concentrations can help to better understand the process of cell proliferation to tumour growth

15-Aug-2022 - Researchers determine the structure and dynamics of proteins using NMR (Nuclear Magnetic Resonance) spectroscopy. Until now, however, much higher concentrations were necessary for in-vitro measurements of the biomolecules in solution than found in our body's cells. An NMR method enhanced by a ...

New spectroscopic insights into hydrogen bonds

Surprising results

21-Jun-2022 - Hydrogen bonds are of fundamental interest in materials science, physics and chemistry. An international team including scientists from the University of Bayreuth has now achieved surprising insights into the formation of hydrogen bonds using a novel method that enables the application of NMR ...

Magnetic resonance makes the invisible visible

Hyperpolarised water boosts signal intensities of proteins, DNA, and membranes

20-May-2022 - A small group of researchers including Dennis Kurzbach from the Faculty of Chemistry of the University of Vienna just published in "Nature Protocols" an advanced NMR (Nuclear Magnetic Resonance) method to monitor fast and complicated biomolecular events such as protein folding. For example, ...

DNAzymes – how active DNA molecules with therapeutic potential work

28-Dec-2021 - DNAzymes are precision biocatalysts that destroy unwanted RNA molecules. However, major obstacles to their use in medicine remain. Together with Jülich Research Centre (FZJ) and the University of Bonn, a research team from Heinrich Heine University Düsseldorf (HHU) has investigated with atomic ...
