METROLOGY OF THE ENMS
The different efforts of metrological analysis in order to offer important contributions in the toxicology of ENM
"METROLOGY OF THE ENMS"
The question that fits in this regard is; What physicochemical properties of nanomaterials should be measured and how?
Through toxicology studies, it became clear that multiple physicochemical properties of ENM could affect the toxicological response. Likewise, the researchers indicated that evaluations of ENMs in workplace atmospheres initially faced the challenge that many sampling and analysis methods were not specific to the ENMs of interest, making it difficult to differentiate them from "background nanoparticles". "incidentals in the air (Methner et al. 2007)
It is necessary to indicate that different studies from the metrology approach have tried to carry out a measurement that is conclusive in terms of physicochemical properties, through tests such as particle size, crystallinity among others, to contribute if they are relevant in terms of the toxicity of these, but they have not generated really valuable and above all conclusive contributions.
More specific analyzes such as electron microscopy have been suggested in conjunction with others such as condensation particle counters and even so they do not develop characteristic data in detail.
