Developing Methods to Measure Release of Nanomaterials From Solid Matrices

There is tremendous potential for nanotechnologies to create new materials and devices for use in medicine, electronics, energy production, cosmetics, packaging, food manufacturing, and many other fields. Governments and industry around the globe are investing billions into research to understand the possibilities and limits of these newer technologies.


The NanoRelease project will foster the safe development of nanomaterials by supporting development of methods to understand the release of nanomaterials used in products.


  • Provide focus to broad policy debates by working through scenarios under which specific engineered nanomaterials might be released from products;
  • Examine the full life cycle of products that might act to release nanomaterials;
  • Catalogue and disseminate published and unpublished data and methods (that meet minimum criteria) used to evaluate release scenarios;
  • Develop “state of the science” reports about release measurement for the specific material types chosen that describe what is known and what research gaps exist; and
  • Enable improvements, standardization, and widespread use of methods by carrying out tests using reference nanomaterial-matrix and positive controls in a “round robin” or similar approach.



The project consists of three phases with the following ultimate goals:


NanoRelease and the National Nanotechnology Initiative’s Signature Initiative Sustainable Nanomanufacturing – Creating the Industries of the Future

The NanoRelease project supports the NNI Signature initiative on sustainable nanomanufacturing and other similar initiatives worldwide by developing broadly accepted methods for measuring release of multi-walled carbon nanotubes throughout the full life cycle of product uses. The development of such methods is a critical prerequisite to the design, prototype, and scale-up product formulations using sustainability evaluations that include full consideration of MWCNT release potential and its EHS implications.
