Release of silver and titanium from face masks traded for the general population.
ICPMS Nanoparticle Risk Assessment Silver textile Abstract: Previous assessments of a selection of face masks intended for the general population in Belgium found that silver (Ag)-based biocides were ...
Application of silver-based biocides in face masks intended for general use requires regulatory control
Christiane Vleminckx; Joris Van Loco; Eveline Verleysen Source: Science of The Total Environment, Volume 870 (2023) Keywords: Ag Biocide electron microscopy Face masks ICPMS Nanoparticle Physicochemical ...
METROFOOD-RI: Pilot services with physical, remote and virtual access
(IBA, Romania). remote access to the transmission electron microscope facility for physicochemical characterization of nanoparticles in food (Sciensano, Belgium). virtual access to two e-services for open data use, ...
Agglomeration of titanium dioxide nanoparticles increases toxicological responses in vitro and in vivo
the influence of nanoparticle (NP) agglomeration and aggregation on toxicity is poorly understood although it is strongly believed that smaller the size of the NP s greater the toxicity. ...
Estimation of the Uncertainties Related to the Measurement of the Size and Quantities of Individual Silver Nanoparticles in Confectionery.
Single particle ICP-MS Abstract: E174 (silver) is a food additive that may contain silver nanoparticles (AgNP). Validated methods are needed to size and quantify these particles in a regulatory context. ...
A systematic evaluation of Flow Field Flow Fractionation and single-particle ICP-MS to obtain the size distribution of organo-mineral iron oxyhydroxide colloids.
and to compare these with standard approaches, i.e. dynamic light scattering (DLS), nanoparticle tracking analysis (NTA), microscopy (TEM), membrane filtration, centrifugation and dialysis. Seven ...
Short-term biodistribution and clearance of intravenously administered silica nanoparticles
concerns have been raised about potential adverse effects of synthetic amorphous silica, commonly used as food additive (E551), since silica nanoparticles have been detected in food containing E551. We ...
Toxicology of silica nanoparticles: an update
H. Source: Archives of Toxicology, Volume 91, Number 3010 (2017) Keywords: Amorphous silica nanoparticles Oxidative Stress Pyrogenic Stöber toxicity Abstract: Large-scale production and use of ...
Biological control of the size and reactivity of catalytic Pd(0) produced by Shewanella oneidensis.
Viability Nanoparticles Palladium Polychlorinated Biphenyls Shewanella Abstract: The interaction between Shewanella oneidensis MR-1 and the soluble metal Pd(II) during the reductive precipitation of Pd(0) ...
