A March 2012 report from RNCOS (an industry research firm) forecasts the global nanotechnology market to reach $26 billion by the end of 2014—representing a CAGR of roughly 19%—driven by expansion of nanomaterials, nanofilms, and nanodevices in all sectors of the economy, including throughout the built environment.
At present, the U.S. remains the largest market for nanotechnology, although many other nations (Brazil, India, and China included) are making sizable investments in R&D for this field. In less than a decade (since the 21st Century Nanotechnology R&D Act was signed into law on December 3, 2003), the U.S. has spent $24 billion on nanotech R&D.
