Atmospheric Soluble Metals Measured at the Gas-Liquid Interface
Atmospheric soluble metals are strongly associated with adverse health effects. However, the monitoring of atmospheric soluble metals requires time-consuming efforts and great expense to complete sampling and detection steps. A new concept of aerosol-into-liquid capture and detection that bridges free-flowing gas and static liquid phases could realize one-step capture and detection via the gas/liquid interface, which presents effective capture of airborne particles down to nanometers size and detection of soluble metals at the nanogram level (Zhao, Y-B., Cen, T., Jiang, F., He, W., Zhang, X., Feng, X., Gao, M., Ludwig, C., Bakker, E., and Wang, J. (2023) Aerosol-into-liquid capture and detection of atmospheric soluble metals across the gas-liquid interface using Janus-membrane electrodes.

This new concept has broad potential in rapid and cost-effective monitoring of atmospheric soluble components to protect human health and can be extended to other applications.
