Autor: Karine Phalyvong, Yann Sivry, Hélène Pauwels, Alexandre Gélabert, Mickaël Tharaud, Guillaume Wille, Xavier Bourrat, James F. Ranville, Marc F. Benedetti
Publikováno v: Frontiers in Environmental Science, Vol 8 (2021)
Motivation for detecting engineered nanoparticles (ENPs) in the environment comes from a need to understand fate and behavior of these materials in natural matrices. The difficulty lies in the low expected ENP particle number concentration (PNC) and

Geochemistry of Engineered Nanoparticles (CdSe/ZnS Quantum Dots) in Surface Waters
Autor: N. Izyan Supiandi, Rute F. Domingos, Marc F. Benedetti, Yann Sivry
Publikováno v: Frontiers in Environmental Science, Vol 8 (2020)
The difficulties when studying the behavior of engineered nanoparticles (ENPs), and the subsequent metal speciation in aquatic ecosystems, at environmentally relevant concentrations (i.e., ppt level) are often related to the occurrence of ENP constit

How Microbial Biofilms Control the Environmental Fate of Engineered Nanoparticles?
Autor: Morgane Desmau, Andrea Carboni, Maureen Le Bars, Emmanuel Doelsch, Marc F. Benedetti, Mélanie Auffan, Clément Levard, Alexandre Gelabert
Publikováno v: Frontiers in Environmental Science, Vol 8 (2020)
Predicting the fate of engineered nanoparticles (ENPs) once they are released in the environment is essential to evaluate their impacts to ecosystems. Microbial biofilms, as highly reactive compartments in soils and sediments, have the potential to i

Detection of nanoparticles by single-particle ICP-MS with complete transport efficiency through direct nebulization at few-microlitres-per-minute uptake rates
Autor: Marc F. Benedetti, Pascale Louvat, Mickaël Tharaud
Publikováno v: Analytical and Bioanalytical Chemistry
Analytical and Bioanalytical Chemistry, Springer Verlag, 2020
Measurement of nanoparticle (NP) concentration and size by single-particle inductively coupled plasma mass spectrometry (spICP-MS) usually requires the use of a NP reference material to determine the loss of NPs and/or ions during their transport fro
