Bacteria can alter the toxicity and affect the biosafety of nanomaterials

By: Editorial Staff* Art by: Livia Bortoletto** The combination of advanced materials with wide technological application, such as graphene oxide, and common substances may increase the accumulation of metals, with environmental consequences – Illustration: Royal Society of Chemistry An international team of researchers discovered that the interaction of nanomaterials with proteins and biomolecules derived from bacteria can alter the behavior and toxicity of substances such as graphene oxide. The study, conducted by Francine Côa during her doctoral research at USP’s Center for Nuclear Energy in Agriculture (Cena), under the supervision of researcher Diego Martinez of the Brazilian Center for Research in Energy and Materials (CNPEM), resulted in an article published in the journal Nanoscale Advances and featured on the cover of the issue.
