a blog by the NSF Center for Sustainable Nanotechnology
Almost 4 years ago now (wow I’m getting old) I wrote a blog post about the Invisible Remnants of Dead Stuff Hiding in the Water called natural organic matter, or NOM. Well, some colleagues and I recently published a new paper entitled “Natural organic matter concentration impacts the interaction of functionalized diamond nanoparticles with model …

Have bacteria ever made you sick? If you answer no I’m not going to believe you. When most of us think about bacteria, we’re reminded of how miserable we were the last time we had strep throat or another bacterial illness. Of course there are many other things that can make people sick, but in …
In this episode, we talk about a recent research study that looked at how one type of battery nanomaterial affects bacteria called Shewanella oneidensis. We interview Mimi Hang and Ian Gunsolus, who were co-first authors of the study as graduate students in the Center for Sustainable Nanotechnology.
Along with eight colleagues (most from the Center for Sustainable Nanotechnology) I recently co-authored an article in the American Chemical Society’s Chemistry of Materials journal titled “Impact of Nanoscale Lithium Nickel Manganese Cobalt Oxide (NMC) on the Bacterium Shewanella oneidensis MR‐1.”1 Just as the name suggests, we analyzed how nanoscale NMC, an important material in some …
Interested in learning more about the study on NMC nanomaterials and bacteria that was discussed in Monday's post? We've had two more opportunities to discuss this Center for Sustainable Nanotechnology research with the media this week, and it's pretty cool to see how each piece explains the work a little differently. Thank you to KARE 11's Jeff …

Last Thursday, the Center for Sustainable Nanotechnology had a brush with mainstream media exposure: A Twin Cities TV station, KMSP: Fox 9, did a story about a recent CSN publication for the 9 o’clock news! The opportunity to get such broad public exposure for our research was really exciting. In the case of Thursday’s TV …

What happens to cells when they come into contact with nanoparticles? Researchers in the Center for Sustainable Nanotechnology are trying to answer this question in a lot of different ways. The effect of exposing organisms to nanoparticles is not as simple as life or death. In one recent study1 we explored the molecular changes that …
