Nano Inventory Tops 1,000: By The Numbers

At its current growth rate nano-enabled consumer products could approach 1,600 over the next two years.

Calls for greater regulation of nanotechnology -- or at least a better understanding of its potential risks -- have been on the rise. The most recent inventory of consumer products containing nanotechnology may indicate why. The latest update to the inventory developed by the Project on Emerging Nanotechnologies (PEN) shows the number of nano-enabled consumer products slid past 1,000, a growth rate of 379% since the list launched in 2006. PEN director David Rejeski says the number of products on the inventory could approach 1,600 in the next two years at its current growth rate.
