The FP7 NanoTest project (www.nanotest-fp7.eu) focused on ENMs used in nanomedicine. As the area of nanomedicine brings humans into direct contact with nanomaterials, data on ENM interaction with cells from eight different organs and tissues were studied. The NanoTEST project is completed and data is available to several ongoing projects (e.g. RiskGone) through the eNanoMapper Nanosafety Data Interface h ps://search.data.enanomapper.net/. Six materials are linked to ERM identifiers, ERM00000068-ERM00000073. Genotoxicity, oxidative stress, cell viability, immunotoxicity and physicochemical characterisation data generated on blood, lung, brain, gastrointestinal tract, liver, kidney, vascular system and placenta models by the project partners can be retrieved using these identifiers.
