Researchers at TU Wien, EPFL, and Invisible-Light Labs have developed a novel nanoelectromechanical infrared sensing workflow, known as NEMS-FTIR, that drastically reduces the time required for aerosol chemistry measurements. This method allows submicrometer aerosol samples, which were previously challenging to analyze due to their small size and low mass, to be measured within minutes instead of days. By utilizing ultrathin silicon nitride resonators as both sampling substrates and detectors, the approach captures real-time variations in aerosol composition, even at high altitudes with tethered balloons.
