The scientists used a Langendorff heart \u2013 an isolated rodent heart flushed with a nutrient solution in place of blood \u2013 to show that nanoparticles have a clearly measurable effect on the heart. The heart reacted to commonly used artificial nanoparticles, such as carbon black and titanium dioxide, with an increased heart rate, cardiac arrhythmia and modified ECG values. Reinhard Nie\u00dfner, Director of the Institute of Hydrochemistry at the TU Muenchen, said, \u201cWe use the heart as a detector. In this way we can test whether specific nanoparticles have an effect on the heart function. Such an option did not exist hitherto,\u201d adding, \u201cWe now have a model for a superior organ that can be used to test the influence of artificial nanoparticles. The next thing we want to do is to find out why some nanoparticles influence the heart function, while others do not influence the heart at all.\u201d The team\u2019s results were published in the journal ACS Nano.<\/p>\n<p><a href=\"http:\/\/portal.mytum.de\/pressestelle\/pressemitteilungen\/NewsArticle_20110729_101739\">http:\/\/portal.mytum.de\/pressestelle\/pressemitteilungen\/NewsArticle_20110729_101739<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Researchers at the Technische Universitaet Muenchen (TUM) and the Helmholtz Zentrum Muenchen, both in Germany, have shown, for the first [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[34],"tags":[],"class_list":["post-2892","post","type-post","status-publish","format-standard","hentry","category-technology-update"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.5 -
