Lots of news stories recently have reported the dangerous effects of nanotubes etc. in the body. Can you comment on the toxicological effects of nanostructures to humans or to the environment? Will new laws be implemented to regulate nanoscale commercial applications because of these effects?

The toxicity of nanostructures to humans or to the environment is a contentious topic. In particular, early reports of carbon nanotube (CNT) toxicity were later shown to result from contaminan....more

I am a student who will be finishing graduate school shortly, and I am worried about the current job climate. What do the job prospects in nanotechnology look like currently? How do these prospective careers compare in different regions around the world?

There are many different areas of nanotechnology. Some industries based on nanotechnology are in a better position at the moment to hire than others. It depends if you are interested in an academic position, an industrial position (big companie....more

What instrumentation or technique developments have made the most significant impact in enabling nanoscience research?

There is no question that the scanning tunneling microscope (STM) has revolutionized science of nanoscale structures by allowing the direct visualization of the atoms (or at least giving a good correlation with their charge density). First ....more
