Nanotechnology has been defined as the control or restructuring of matter at the atomic and molecular levels in the size range of about 1–100 nanometers (nm); 100 nm is about 1/1000th the width of a hair.
The U.S. National Nanotechnology Initiative (NNI), begun in 2001 and focusing primarily on R&D, represents a cumulative investment of almost $20 billion, including the request for fiscal year 2014. As research continues and other nations increasingly invest in R&D, nanotechnology is moving from the laboratory to commercial markets, mass manufacturing, and the global marketplace. Today, burgeoning markets and nanomanufacturing activities are increasingly competitive in a global context—and the potential EHS effects of nanomanufacturing remain largely unknown.
GAO was asked to testify on challenges to U.S. competitiveness in nanomanufacturing and related issues. Our statement is based on GAO’s earlier report on the Forum on Nano-manufacturing, which was convened by the Comptroller General of the United States in July 2013 (GAO 2014; also referred to as GAO-14-181SP). That report reflects forum discussions as well as four expert-based profiles of nano-industry areas, which GAO prepared prior to the forum and which are appended to the earlier report
