摘要: Distinguishing nanomaterials of interest from background nanosized matter already present in the sampling environment is a challenging task. In this study, we propose use rare earth elements (REEs) as high-sensitivity labels to identify and monitor their fate following manipulation. The REE were added during synthesis TiO2 nanoparticles with hydrodynamic sizes 15 nm. REE-labelled allow monitoring nanoparticle aerosols formed handling nanoparticulate materials glove box. deposition labelled on working surfaces could be verified by electron microscopy surface analysis, using presence lanthanide an identification label. total amount deposited material quantified procedure based wiping area followed digestion collected analysis flame emission spectrometry.
