Isotopic labeling of nanoparticles for the evaluation of their environmental fate in mesocosm experiments.

Mesocosm systems simulating floodplain areas are essential for the understanding of the environmental fate and effects of engineered nanoparticles (ENPs). In such mesocosm studies, the quantification of different types of nanoparticles coexisting in natural systems and containing the same element is often challenging. Such coexistence is expected e.

Generation, characterization, and toxicological assessment of reference ultrafine soot particles with different organic content for inhalation toxicological studies.

Ultrafine particles (UFP) are the smallest atmospheric particulate matter linked to air pollution-related diseases. The extent to which UFP's physical and chemical properties contribute to its toxicity remains unclear. It is hypothesized that UFP act as carriers for chemicals that drive biological responses.

Multi-Parameter Analysis of Nanoplastics in Flow: Taking Advantage of High Sensitivity and Time Resolution Enabled by Stimulated Raman Scattering.

Here, we demonstrate the detection of nanoplastics (NPLs) in flow with stimulated Raman scattering (SRS) for the first time. NPLs (plastic particles <1000 nm) have recently been detected in different environmental samples and personal care products. However, their characterization is still an analytical challenge.
