However, when it comes to nanoparticles, the weight of the nanomaterial is not a relevant parameter, especially when it is required to compare different kinds of nanoparticles \u2013 such as carbon or metals for example \u2013 because their density is very different. In a recent study, Flahaut and his collaborators show that that the usual approach based on mass concentrations fails to compare the toxicities of different engineered carbon nanoparticles (C-NPs).They report their findings in the April 28, 2016 online edition of <em>Nano Letters<\/em> (\"<u><a href=\"http:\/\/pubs.acs.org\/doi\/abs\/10.1021\/acs.nanolett.6b00348\" target=\"_blank\">Surface Area of Carbon Nanoparticles: A Dose Metric for a More Realistic Ecotoxicological Assessment<\/a>\"<\/u>) The most significant result of this study is that the researchers demonstrate that the surface area can be used as a relevant metric to compare the toxicity of different kinds of carbon nanoparticles, but more importantly, for the first time that it can even <em>a priori<\/em> also be used as a criterion for predicting the toxicity \u2013 at least in the team's experimental conditions \u2013 of carbon nanoparticles, ranging from 0D to 2D.<\/p>\n<p>Source: <a href=\"http:\/\/www.nanowerk.com\/spotlight\/spotid=43493.php\" target=\"_blank\">Nanowerk<\/a><\/p>\n<p>Image source: <a href=\"http:\/\/pubs.acs.org\/doi\/abs\/10.1021\/acs.nanolett.6b00348\" target=\"_blank\">Flahaut et al.<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Researchers show on the example of carbon nanoparticles that the surface area is suited much more for a measure of toxicity of nanoparticles compared to traditional measures such as weight concentrations.<\/p>\n","protected":false},"author":22,"featured_media":11747,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[43],"tags":[],"class_list":["post-11749","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-nanotechnology"],"_links":{"self":[{"href":"https:\/\/innovationsgesellschaft.ch\/en\/wp-json\/wp\/v2\/posts\/11749","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationsgesellschaft.ch\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/innovationsgesellschaft.ch\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/innovationsgesellschaft.ch\/en\/wp-json\/wp\/v2\/users\/22"}],"replies":[{"embeddable":true,"href":"https:\/\/innovationsgesellschaft.ch\/en\/wp-json\/wp\/v2\/comments?post=11749"}],"version-history":[{"count":2,"href":"https:\/\/innovationsgesellschaft.ch\/en\/wp-json\/wp\/v2\/posts\/11749\/revisions"}],"predecessor-version":[{"id":12254,"href":"https:\/\/innovationsgesellschaft.ch\/en\/wp-json\/wp\/v2\/posts\/11749\/revisions\/12254"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/innovationsgesellschaft.ch\/en\/wp-json\/wp\/v2\/media\/11747"}],"wp:attachment":[{"href":"https:\/\/innovationsgesellschaft.ch\/en\/wp-json\/wp\/v2\/media?parent=11749"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/innovationsgesellschaft.ch\/en\/wp-json\/wp\/v2\/categories?post=11749"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/innovationsgesellschaft.ch\/en\/wp-json\/wp\/v2\/tags?post=11749"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
