Effizientere Risikobewertung von Nanomaterialien

UFZ-Forscher analysieren biologische Wirkungsmechanismen und finden Biomarker

(PresseBox) (Leipzig, )
Die Nanotechnologie boomt. Doch die Risikobewertung dieser winzigen Partikel ist aufwendig und stellt das Bundesinstitut für Risikobewertung (BfR) vor große Herausforderungen. Forscher des Helmholtz-Zentrums für Umweltforschung (UFZ) haben nun in Kooperation mit Wissenschaftlern des BfR nach Ansatzpunkten für effizientere Testverfahren gefahndet und dafür die biologischen Effekte genauer unter die Lupe genommen. Ihre Ergebnisse sind im Fachjournal Particle and Fibre Toxicology veröffentlicht.

Ob in Farb- oder Baustoffen, Kosmetikprodukten, in der Elektronik oder der Medizin - Nanomaterialien werden heute vielseitig eingesetzt. Doch was für Stoffe sind das eigentlich? "Nanomaterialien definieren sich allein über ihre Größe", erklärt Dr. Kristin Schubert vom Department für Pwcwpncuss Ceeiydxuspswba ex BJV.
