Uptake of tire wear additives by vegetables grown for human consumption

Chemical residues from tyre wear detected in leafy vegetables for the first time

06-Jun-2024 - Car tires contain hundreds of chemical additives that can leach out of them. This is how they end up in crops and subsequently in the food chain. Researchers at the Center for Microbiology and Environmental Systems Science at the University of Vienna and the Hebrew University of Jerusalem have ...

Superconducting Nanowires Detect Single Protein Ions

Detection efficiency 1,000 times higher than conventional ion detectors due to high sensitivity

08-Dec-2023 - An international research team led by quantum physicist Markus Arndt (University of Vienna) has achieved a breakthrough in the detection of protein ions: Due to their high energy sensitivity, superconducting nanowire detectors achieve almost 100% quantum efficiency and exceed the detection ...

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 ...

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, ...

Environmental exposures affect therapeutic drugs

High-resolution mass spectrometry promotes new methods for analysis

16-Dec-2020 - Humans are exposed to various environmental or dietary molecules that can attenuate or even increase the effect of therapeutic drugs. Studies on the industrial chemical bisphenol A and the phytoestrogen genistein, for example, have shown drug-exposome interactions. However, interactions between ...
