Surface characterization of gold nanoparticles for nanomaterial specific toxicity screening: FT-IR method Ingestion-build-207047 and that carcinogenic or sensitizing1 Scope This Technical Specification provides guidelines for the identification of the surface bound molecules using FT IR of dehydrated gold nanoparticle (AuNPs) films both before and after nanomaterial (NM) cytotoxicity testing. NOTE 1 AuNPs may have surface bound ligands prior to testing and may be additionally covered (or coated) with organic or bio molecules during the cytotoxicity test. NOTE 2 Nucleic acids, amino acids, lipids or membrane
