Our new @ACS_Omega paper uses real-time fluorescence anisotropy to benchmark metal chelators (Ni-Bme-Dach vs EDTA) exposing mechanisms static assays miss. doi.org/10.1021/acsomega.5c1… #BioinorganicChemistry #AlzheimersResearch

Our new paper in Small challenges a key assumption in nanomaterial safety: less ion release doesn’t necessarily mean less toxicity. In cobalt-gold nanoparticles, biointerface persistence better explained the observed response. doi.org/10.1002/smll.75247 #Nanotoxicology

Decoupling Ion Release from Biointerface Persistence in Redox‐Active Cobalt Nanoparticle Toxicity...

Chemical stabilization alters nanomaterial exposure behavior by decoupling cobalt ion release from biological response. A structurally controlled cobalt–gold nanoparticle series demonstrates that...

Earlier this term our NSF-funded Ignite inSTEM camp was highlighted and celebrated for inclusive excellence on the State of Diversity at @OregonState Check out our story: diversity.oregonstate.edu/al… and here is more about it. media.oregonstate.edu/media/…

Sparking excitement in STEM is easy. Providing access often isn't.

Ignite inSTEM does both. Story by Becky Barrett Marilyn Mackiewicz believes in the power of what she calls “ooh ah” moments. They can be created using the latest instrumentation to change the color...
