How Natural Organic Matter May Change How Nanoparticles Affect Bacteria

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 …

Nanoparticles can stick to bacteria, but does more nanoparticle sticking mean more toxicity?

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 …

Battery Behavior in the Biosphere: How We Probed Nanoscale Battery Materials Interacting with Bacteria

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 …

More Media Coverage for NMC Paper

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 …

Using Gene Expression to Learn About Nanoparticle Toxicity

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 …
