Significantly improving the "sense of smell" of molecular laser spectroscopy: Increases chances to reliably detect diseases

25-Aug-2022 - Sensitive animal noses can sniff out trace particles, such as volatile organic compounds, in the ambient air. Humans, on the other hand, are developing innovative technologies for this purpose, such as optical spectroscopy. This uses laser light to detect the molecular composition of gases. It ...

New label-free detection technique digitally counts intact SARS-CoV-2 virus particles in saliva or exhaled breath

25-Jan-2022 - As health and research institutions continue to rapidly develop new methodologies for detecting SARS-CoV-2, researchers from the Holonyak Micro & Nanotechnology Laboratory have found themselves at both forefronts of discovery and featured on the cover of the Journal of the American Chemical ...

Detection of cancer from exhaled breath

Breath gas analysis for medical diagnostics

03-Dec-2020 - The air we exhale contains information that can assist with the diagnosis of disease. Researchers at the Fraunhofer Project Hub for Microelectronic and Optical Systems for Biomedicine MEOS are now developing solutions designed to enable the analysis of breath gas for this purpose. Although their ...

Measuring ethanol’s deadly twin

18-Sep-2019 - ETH researchers have developed an inexpensive, handheld measuring device that can distinguish between methanol and potable alcohol. It offers a simple, quick method of detecting adulterated or contaminated alcoholic beverages and is able to diagnose methanol poisoning in exhaled breath. Methanol ...

Cancer diagnosis with a breath test

A new test for the early detection of lung cancer measures tiny changes in the composition of the breath

21-Apr-2017 - “Inhale deeply ... and exhale.” This is what a test for lung cancer could be like in future. Scientists at the Max Planck Institute for Heart and Lung Research in Bad Nauheim have developed a method that can detect the disease at an early stage. To this effect, they investigated the presence of ...
