Chemical and Engineering News recently published an article "Challenge of Risk-Based Nanotech Research" which provides some insightful quotes from Kristen Kulinowski, Director of the International Council on Nanotechnology at Rice University. Dr. Kulinowski pointed out "There are just too many types of nanoparticles all under the broad umbrella of nanotechnology to make any blanket statements about their interactions wit, say, a cell or tissue…. Even if we focus on one type of nanoparticles like carbon-based ones, there is still an unbelievable variety of nanostructures that can be created."  We agree with Dr. Kulinowski and urge "gloom and doom" advocates to take note.
