Defense Applications of Nanotechnology
Extraordinary potential benefits…
Unknown human and environmental safety and health (ES&H) risks
Protecting Nanotechnology Users
Impossible to evaluate risks of all
nanoparticle (NP) variants
Data linking NP structure to behavior
and activity is emerging, but scattered
Informatics approaches needed to help
predict, mitigate risks

Streamlined curation of ecotox and mammalian tox data
Cross-citation data trends
Development of predictive modeling tools
– Classical QSARs/QSPRs
– Alternative approaches for heterogeneous data
Logical classification of nanoparticles based on:
– Elemental composition
– Properties
– Toxicity
Current focus on defense applications of
nanotechnology
