Posted Sat May 3 2008: from Georgia Institute of Technology, via EurekAlert:
Environmental fate of nanoparticles depends on properties of water carrying them
The fate of carbon-based nanoparticles spilled into groundwater -- and the ability of municipal filtration systems to remove the nanoparticles from drinking water -- depend on subtle differences in the solution properties of the water carrying the particles, a new study has found. In slightly salty water, for example, clusters of Carbon 60 (C60) would tend to adhere tightly to soil or filtration system particles. But where natural organic compounds or chemical surfactants serve as stabilizers in water, the C60 fullerene particles would tend to flow as easily as the water carrying them. "In some cases, the nanoparticles move very little and you would get complete retention in the soil," said Kurt Pennell, a professor in the School of Civil and Environmental Engineering at the Georgia Institute of Technology. "But in different solution conditions or in the presence of a stabilizing agent, they can travel just like water. The movement of these nanoparticles is very sensitive to the solution conditions."

Hmm. I think I'm made of "slightly salty water." But then, I'm also "natural organic compounds."
Will it nanostay or will it nanogo?
