NanoHealth and Safety

Program Description 

At the National Institute of Environmental Health Sciences (NIEHS), a unique combination of knowledge, expertise, and a commitment to understanding the role of environmental exposures in human disease enables novel approaches to the study of nanomaterials and their potential impact on human health, or nanohealth. The critical research challenges for nanoscale materials - determining dose, assessing biological response, and quantifying exposure and risk - are the same challenges on which the NIEHS has built its reputation. Recognizing that engineered nanomaterials are quickly surrounding us in the products of our daily life such as drugs, cosmetics, electronics, and more, the NIEHS began to delve into this area of research several years ago, and is continuing to expand the inquiry into this emerging and important field. The outcome of these efforts will be the design of nanomaterials that are both innovative and safe for commercialization in medical, industrial, and consumer products.


The NIEHS is engaged in a collaborative effort with the National Institute of Biomedical Imaging and Bioengineering to develop the critically needed bioinformatics framework for nanohealth and safety research data.



The NIEHS has been working to encourage and support research into the underlying properties of engineered nanomaterials (ENM) to determine their potential biocompatibility or toxicity to human health. Recent grants, funded in partnership with other NIH institutes and federal agencies, are helping to build the foundation of our understanding of how the unique chemical and physical properties that emerge at the nanoscale may affect the interactions between environmental exposures and the body.
