Two decades after the federal government jumpstarted U.S. R&D investment in its understanding and control of nanoscale matter, funding for the efforts across the government reached about $1.4 billion in fiscal 2020, part of a total cumulative investment of about $29 billion. Though FDA-budgeted nanotech research has accounted for just a fraction of that, at a modest $133 million since 2009, substantial advances have still been made, according to a presentation on the state of nanotech progress and innovation issued this summer.
