The US nanotechnology industry, currently passing around its begging bowl on Capitol Hill should perhaps take a hint from Edward Cupoli, an economics professor at the State University of New York at “Albany’s College of Nanoscale,” who told reporters
“Consumers are hungry for nano-size innovations. The market is driven primarily by young, tech-savvy consumers who demand more and more functionality from smaller equipment. If they produce it, the market is there.”
In plain language that is just “make stuff and sell it to people,” that way you might be able to do an IPO without relying on government funds.
