The U.S. Chamber of Commerce is the latest organization to wade into the nanotechnology pool and host a forum to discuss issues of concern to members.  With apologies for the late notice, the Chamber will host the symposium Breaking the Barriers: The BIG Business of Nanotechnology today (November 13, 2007) at its Headquarters to discuss "the major barriers of nanotechnology commercialization" as well as regulatory concerns and consumer education.  The Chamber is located at  1615 H Street NW in Washington, D.C., and a live webcast can be found here.
