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. ...

Bepaling van spoorelementen in diverse matrices met spectrometische technieken.

has shown that Ti nanoparticles are contained in the fibers. Conclusion Only low concentrations of trace elements were found in most of the food enzyme preparations studied. The information collected ...

Validation of single particle ICP-MS for routine sizing and quantification of the fraction of silver nanoparticles in E174 food addititves and confectionery products

and in liqueurs [1]. It is commercially distributed in its pristine powder and sheet form, and in confectionery products. Due to its nature, E174 may contain silver nanoparticles, which implies a need ...

Physicochemical characterisation of several types of the E171 food additive

food products containing E171. All examined E171 food additives contained a significant amount of nanoparticles. In the most dispersed state, the particle size measurements by TEM and sp- ICP- MS agreed ...

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 ...

Physicochemical Characterisation of the E171 Food Additive

and it was demonstrated that all examined E171 food additives contained a significant amount of nanoparticles. The large majority of constituent particles, confirmed to be TiO2 by energy dispersive ...
