Toxicity
ERDC cell screening and surrogate bioassays are used to assess the potential toxicity of nanomaterials to humans. A broad range of terrestrial and aquatic bioassay tests are used to determine ecotoxicity of nanomaterials. These methods are used to generate high quality toxicological data tailored to specific nanomaterials and nanotechnology. Toxicity assessment capabilities provide standardized and customized methods to predict effects in complex environmental systems.
ERDC uses mixed alveolar cell and macrophage cultures for in vitro screening of nanoparticle toxicity
Exposure, uptake, and ecotoxicity of nanoparticles are determined using a wide range of invertebrate and vertebrate bioassays
