Widely varying particle behavior raises nanotechnology concerns

The tiniest particles of matter don't flow in uniform ways in water, a finding that could have wide-ranging implications in assessing the environmental risks and benefits of nanotechnology, the science of manipulating the very small, a scientist said Thursday. The preliminary research, the first of its kind, suggests that the ways in which so-called nanoparticles behave in groundwater environments or water treatment plants are as varied as are the diverse molecules or atoms used to assemble them.
