New Insights on controlling nanoparticle stability

Beverly Smith's and Jim Hutchison's paper published in the Journal of Physical Chemistry C (27 November 2013) studying the structure of ligand-stabilized gold nanoparticles have captured fundamental new insights about their stability. The information, they say, could help to maintain a desired, integral property in nanoparticles used in electronic devices, where stability is important, or to design them so they readily condense into thin films for such things as inks or catalysts in electronic or solar devices.

How Tiny Fish Could Reveal Effects of Chemical Exposure

Elizabeth Grossman, author of Chasing Molecules: Poisonous Products, Human Health wrote a very nice article about Robert's work in environment 360. We first met Ms. Grossman at one of our GN Conferences, when she was researching material for her book. 

From the Zebrafish to you

Robert Tanguay's work is showcased in the 2 July Issue of Terra Magazine. "On average, an individual encounters about 80,000 synthetic chemicals every day."

Online Nanomaterial Registry Expands, Prepares for 'Big Data'


RTI International recently added hundreds of new data records to the Nanomaterial Registry, an authoritative, web-based resource that organizes and evaluates the biological and environmental implications of well-characterized nanomaterials from publicly available resources.

The Nanomaterial Registry, available free to the public at, allows users to search, browse and compare data on the characteristics of a wide variety of nanomaterials.

Quantum Dots: From Lab to Market

SNNI will host a special materials chemistry seminar on Wednesday, April 17, at 3:30 in 331 Klamath Hall. 

Model examines nanotoxicity in different ionic strength media

Because of the widespread use of silver nanoparticles (AgNPs) in anti-microbial consumer products there are growing concerns regarding exposure to these materials and potential risks to humans and wildlife. Despite a large number of experiments, the toxicity of AgNPs is still largely unknown. This is partly because of the fact that AgNPs agglomerate differently depending on the media in which they are found, which makes it difficult to assess the inherent toxicity of these nanostructures.

Fluorescence SIM available at EMSL

A new super resolution fluorescence structured illumination microscopy system, or fluorescence SIM, is now available at EMSL as part of the lab’s Cell Isolation and Systems Analysis capabilities. Access to the new instrument is through EMSL’s user proposal process. The EMSL Usage System lists it as Microscope: Fluorescence, Super Resolution Structured Illumination.

Silver nanoparticle shedding

"Nanotechnology, naturally delicious!" In a recent news article by InterNano, Dr. Scott Rickert compiles some tasty facts about nanoparticles in food that dates back to the Egyptians. In his article he mentions some of SNNI's research and a cool video posted by Chemical and Engineering News on that research.
