Studying How “Green” Nanotechnology Can Be

Larval fish (the fathead minnow) used in a study of nanotoxicology by Matthew Hull et al. Matthew Hull, founder of NanoSafe, Inc., a VT KnowledgeWorks member company, was featured in a Nanowerk Spotlight, Nanowerk's "nanotechnology feature [that] looks behind the buzz and the hype…[to] what's new and hot around the globe."

The Nanowerk Spotlight, Not so 'green' nanotechnology manufacturing, explores the implications of the paper by Hull et al., Release of Metal Impurities from Carbon Nanomaterials Influences Aquatic Toxicity, on environmental impacts of impurities and byproducts associated with nanomanufacturing processes.

In their study, Hull and colleagues studied whether feedstock metals associated with the production of these materials can become mobilized and reach toxic concentrations in simulated aquatic systems.

According to Matthew Hull, "As these results demonstrate, management of nanotechnology wastes will factor heavily into emerging nanomanufacturing activities.  Consequently, NanoSafe, Inc. has positioned itself to provide waste management solutions for generators of these wastes."
